RV Humidity -- A Real Rig Killer!

A strong title, but true.  One of the major killers of RV walls is moisture in the form of humidity.  You don't even have to be using your RV it can be sitting in storage and humidity can still be present on the inside above a safe level.  Mold depends on moisture to grow and flourish. What is a person to do?  Well, the safe level of humidity for an RV is 40% or thereabouts.  So the first thing you need to do is know your current humidity level and the best way to know that is with a humidity monitor.

Humidity Monitor

In the photo for the Humidity Monitor, the screen is showing 53% which is not acceptable for an RV.  The reading shown is more likely a Sticks&Bricks house.
Now that you know what the humidity is.  What can or should you do if it is not right.  You need to try and find out the source of the moisture causing the high humidity.  People give off moisture when we breathe, but getting rid of all the kids is not an option be they fur or not.

Next showers or taking a bath gives off moisture.  Be sure that the bathroom fan is turned on during the bathing process, even in the colder months.  Wipe down the shower and bath area to reduce the amount of moisture that is evaporated back into the air of the RV.

Cooking is another moisture generator.  Keep lids on pans when cooking, to keep the moisture down, open a window a bit to let the warm moist air out, and turn on the kitchen vent if you have one.  Many of the newer RVs do not vent the stove vent to the outside.  This is not good, as an inside vented stove hood keeps the moist air inside the RV.  Do not let a tea kettle steam longer that is necessary.  Don't leave a coffee pot running all day long.  Make a cup as you need it or the coffee pot will add to the humidity in the RV all day long.

Try to locate any seals in the RV slides that is letting in outside air and seal that area.  You can cut strips of foam insulation like Reflectix or other foam insulation.  If you find caulking around the tub or shower stall or even around the kitchen/ bathroom sink is missing or cracking re-caulk using 100% silicone sealant like shown below.  This keeps water from going in the RV wood structure or supports where, if conditions are right, mold will start to grow.

100% Silicone Sealant

If it is during the colder months and your RV has single pane windows you might add Bubble Wrap to the windows.

Bubble Wrap

To install the bubble wrap do the following.

Cut the bubble wrap to the size of the window pane with scissors.
Spray a film of water on the window using a spray bottle.

Spray Bottle

Apply the bubble wrap while the window is still wet and press it into place.
The bubble side goes toward the glass.
To remove the bubble wrap, just pull it off starting from a corner.

This bubble wrap will help insulate the inside of the window from the outside of the window to further reduce moisture forming on the inside of the window when the outside air is colder than the inside air.

Do you dry clothes in the RV by hanging them in the bathroom?  Did you remember to turn on the exhaust fan?  It is not wise to dry clothes in the RV during the colder months because drying clothes adds to the amount of moisture inside the RV.  Do you have a combination washer/dryer?  Make sure the dryer is vented to the outside.  If you do not the dryer will add to the moisture in the RV.

If it possible let the RV inside temperature drop a bit in colder weather so the air inside the RV will hold less moisture.  Cooler air holds less moisture than warm air.  You may have to dress a bit warmer, but your RV investment will thank you for being a bit cooler.

Poor air circulation inside the RV can make mold grow in drawers, closets, and even cabinets.  Keep the air moving even when you are not inside your RV.  How may you ask? You can open two or more roof vents or a roof vent and crack a window so that air naturally flows in and out.  You can add a MaxxAir vent cover

MaxxAir Vent

over your current roof vents so that you can keep your vents open without rain or snow coming in the RV when the roof vent is open. You should put your RV in storage with vents cracked a little bit to allow for air movement.

If your RV does not have LED lighting you could swap out your current incandescent light bulbs for the LED equivalent.  This will reduce the about of air heating that the hotter incandescent bulbs are known for.  There is an LED replacement light for most all of the RV incandescent bulbs used in RVs. As an additional benefit, your RV battery will last longer during dry camping with LED lighting and depending on the LED light you buy you may find that the inside of your RV is now brighter with the lights on.

OK, we have talked about what not to do and some of what you can do to reduce moisture in the RV now let's get serious about stopping or greatly reducing moisture in your RV.
1. Get a dehumidifier.  They come in several sizes and types.
The ezest one to do business with is the bead type.

Eva-Dry Dehumidifier Beads

Twin Pack resealable packaging
100% silent operation
Lasts 45-60 Days
Indicator beads let you know when it's ready to be discarded.

You can spot these around the RV and in closets, cabinets, drawers where ever you feel or think moisture may be lurking.
Next, you have the mechanical dehumidifiers.

Eva-dry Electric Petite Dehumidifier Edv-1100, White

Whisper quiet
Renewable reservoir
Compact size is perfect for bathrooms, closets, and R.V.s
Low energy consumption
One of these usually works but if you have a severe problem you may want to consider two of them.

If you have an RV more than 36 feet long you may want to consider this one.

Ivation IVADM35 Powerful Thermo-Electric Dehumidifier

Squeezes Up to 20 oz. of Water a Day From Humid Air
Very Quiet Operation Due to No Moving Parts
At Capacity, Indicator Lights Up and Device Shuts Off
Compact at 4.45 pounds, 6.8" x 8.5" x 14"
For bunkhouse RVs,  you will need two.

And if you really need more moisture removal you can use a sticks and bricks type unit.

Keystone Energy Star 70 Pt. Dehumidifier

Removes up to 70 pints of moisture from the air per day
1.3-gallon water tank with transparent water level indicator, full bucket alert, and automatic shut-off when full
Removable, easy-cleaning dust filter with a clean filter alert
4 durable, rolling casters for easy movement

 It is generally felt that combinations of dry and mechanical work the best.

Well, that should about do it for this topic.  I hope you found the information helpful and can use some of the ideas presented.

RV Security On The Road And In Storage

It is that time of year again when most of us will have to store our RVs until next Spring. We all do the Winterizing like we are suppose to.  But how many of us even worry about someone coming along and stealing our RV?  Well, we should.  Let's take a look at what you can do to protect your, very expensive RV from being stolen.
Because I live in the city, I can't store my Open Range 3X anywhere on my property or on the street. So like a lot of city dwellers I have to put my RV in storage when I am not using it.  To my shock and amazement, two units were stolen right out of the storage lot that I use.  To add insult to injury, the storage lot had a guard on site, a security system for entrance, and security cameras.  But the same guy managed to get two units out of the locked lot.  Well, thanks to the security cameras they caught the guy.  But what can you and I do to make our units harder to steal and more secure.  Let's look.





First, we can add a lock to the ball area of a TT and a 5th Wheel Hitch Lock. Let's look at both.  The TT ball lock looks like below.

TT ball lock

• One size fits all (from 1-7/8", 2", to 2-5/15", all coupler types)
• Keyhole cover slides up to seal out dirt and grime
• Type A key which is a spring loaded, 7 pin, high-security key. Resists attempted drill outs. Rugged and durable, the key will not bend or break.
• Huge 6 tooth, 3/8" dual ratchet locking system
• Hardened 5/8" 16mm steel shackle

Now that should slow down anyone trying to take the TT quickly.  Now let's look at what can be done to slow down the would-be thief stealing a 5er.  See below for the 5th Wheel Anti-Theft device

5th Wheel Anti-Theft device

This unit slides over the hitch pin and prevents the hitch pin from being attached to, by the hitch receiver. Simple but effective to slow down our would-be thief.

I think we could do more. How about we lock the tires so the RV cannot be moved without putting new tires on the RV? Shown below is an RV Dual Wheel Stop with Padlock

 RV Dual Wheel Stop with Padlock

• Secure tandem tires to prevent movement while parked or re-hitching
• Fits 26" to 30" diameter tires with tire spacing of 3-1/2" to 5-1/2"
• Includes, padlock
• Easy grip handle for easy installation
• Lightweight and durable

This should slow them up but what about something even better?  Let's look at the X Wheel Stop with Padlock.

 X Wheel Stop with Padlock.

While the lock for this heavy-duty unit is extra (a Master Lock, that you supply) it will be well worth it if it slows down someone trying to take your RV.  In most cases, if it is hard to take or time-consuming to take the thief will move on to easier pickings.

We have protected (to the best of our ability) someone trying to take your RV but what about protecting the expensive stuff inside the RV and in the storage bay.  Let's take a look on how to help protect those areas.

First the entrance doors.  Did you know that the key to your RV has been duplicated many times by the manufacturer of your RV?  Did you know that almost any thief can come up with a key that fits your RV doors?

So let's look at a lock that is a bit safer. The Keyless RV Door Lock

Keyless RV Door Lock

• No wiring needed; uses 4 AA batteries (not included) It's retrofittable in most RV entry doors and it's easy to install.
•  Programmable with a 4 digit PIN number The large buttons are easy to see and use Proximity sensing which illuminates the buttons.
• Self-contained electronic RV latch with Capacitive Touch Technology
• Offers hassle-free touchpad access: no key or fob to carry with you.
• An integral touchpad to the latch which controls the deadbolt
• Deadbolt key will always be able to operate the paddle or deadbolt lock in case of the user forgetting the code or having a dead battery, 8-inch x 5-inch x 4-inch.

You don't even need a key to get this lock to open after you enter your personal pin number.  So it will not be a big deal if you lock your keys in the RV. By mistake, of course.

Let's take a look at the outside storage compartment locks.  Did you know that's the lock code for your storage compartment lock is CH751?  This is the most common lock used on TT and 5th wheels today.  So anyone can get in. Let's look at a better idea. The RV Storage Compartment Combi Lock.

RV Storage Compartment Combi Lock

• Cylinder length 1-1/8"" - accommodates material thickness up to 7/8" thick
• Durable solid metal
• 1,000 possible combinations- set your own code
• Retrofits any standard cam lock
• Comes with 3/4" prong washer, 1-1/2" offset cam, 3/4" straight cam, 1-1/2" straight cam and a 90 degree stop.

This type of lock is a direct replacement to what comes on most TTs and 5ers. You take off the old one and measure the hole opening and the length of the shaft and order the same size as the one you have.

Follow the installation instructions and you are done. A really simple install.

Pressure And More Pressure On Your RV's Water Lines

Are you putting to much water pressure on your RV's PEX water lines and their PEX fittings?  Do you know how much pressure you can put on your RV's water lines and their  PEX fittings?
Let's take a look and see what's what.








RV manufacturers typically use PEX  PlasticTubing for all RV plumbing runs. The two sizes are commonly used, 3/8-inch and 1/2-inch. These are the standard size because the outside diameter of the tubing is about 1/8-inch greater than the called-for size. Red PEX is usually the Hot water line and Blue or Clear the cold water line.  But, not always.  There are special fittings used with this type of water line called PEX fittings.  Below are some examples of some fittings you might see under one of your sinks.

The fittings can be of any color or even colorless but they will all have the ribs you see on the fittings above.  You will also note that each PEX fitting has a crimped ring around it.  The ring looks like below.

To put the ring on the PEX tubing and secure the ring you would need a crimping tool.  Shown below.

OK, now that you understand what you currently have let's discuss the problems this type of system brings the RVer.  The whole system can leak at any time and usually does. Every connection, if it is not put on correctly, will leak at the worse possible time. Ah, you say no problem I will just squeeze the ring with my trusty pliers.  Well, your trusty pliers will not be able to squeeze the connector hard enough to seal the leak in most cases.  What to do?  Change the fitting to a more updated connector.  We will cover that in just a minute.

Why do these cheap PEX products not work well all the time?  PRESSURE, water pressure from campgrounds varies greatly and can not.  The PEX water system in an RV cannot safely go above 65 pounds of water pressure.  I will not allow mine to go over 55 pounds of pressure.  

How do I control the RV Parks water pressure with a brass water pressure regulator? 

Brass RV Water Regulator

 You can adjust this type of regulator to any safe water pressure you like for your RV.  This type of regulator does not affect the flow of the water just the pressure. There are lesser expensive water pressure regulators like the one shown below.

Fixed Water Pressure Regulator

While this type will regulate the water pressure it also affects the flow of the water which some people find objectable.  Either one will protect your RV water system from to much PRESSURE.

OK, you just found a PEX fitting under the kitchen island that is leaking now what can you do to fix the problem and how much time is it going to cost you?

You should carry a few Shark Bite connectors like the ones shown below.

Shark Bite Coupler

Shark Bite T

Shark Bite to Threaded 

There are even more fittings to choose from but you get the idea.  The advantages of these types of connector are, 

• INSTALLS IN SECONDS: 1/2 inch straight coupling requires no special tools, no soldering, no crimping or glue. Just push to create a watertight seal

• COPPER, PEX, CPVC: SharkBite straight coupling plumbing fittings fits copper tubing, and CTS CPVC and PEX and connects all three types in any combination

• CERTIFIED: SharkBite fittings are certified to 200 PSI and 200°F and can be reused up to four times

Now doesn't that beat the PEX connector and all the fuss it would take to fix a leaky connection?

The real story here is to control your water pressure coming into your RV.  If you do not you will find leaks and under the shower or under sink water damage.  

One other thing you may want to add a water shutoff to your toilet so in case you need to work on it you do not have to shut off all the water to the RV.

Is It Level??? Is It Stable???

Is It Level??

How many times have I heard that phrase at a campground?  I can't even count them or remember them for that matter.  How do you know when your rig is level and what can you do if your rig is not?
Let's look at some of the possibilities.






The first thing you need to do is eyeball the site that you will back into or pull forward into.
Does the site appear flat?  There could be a drainage crown to the site, meaning that the center is higher than either side so that the rainwater will drain off quickly if it does rain.
Maybe there is a slope in the site toward the right or left.
All of this needs to be taken into consideration when looking at the site.
Ok, you are pulling or backing into the site and you have the support of a ground crew so getting into the site is not the problem.  The door side of the rig appears lower that the street side or is it?   How do you know? Well at some point in the life of your rig someone should have put bubble levels on it.
(For you guys with money we will discuss auto leveling equipment at the end.)

They should look like theses RV Bubble Levels

RV Bubble Levels 

If you have nothing, or what you have is so small as not to be readable then an up-grade is in order.  You should mount one of these in the front of the rig where the level can be easily seen, after taking the rig to a Walmart type parking lot and using a construction level, checking that the rig is sitting truly level before you mount the above levels to the rig.  The second level is mounted on the street side of the rig at the same height that you mounted the front of the rig level.  Be sure you have confirmed that construction level and the RV level agree that the rig is level.
Why you ask?  Because if you are more that 5 degrees out of level your RV refrigerator may not work or will not work efficiently.
But you may not have a TT maybe you have a 5th wheel and need something a bit bigger.  Enter the 5th wheel bubble level.  This is mounted on the pin box so you can see the level from the driver's seat.

5th Wheel Bubble Level

Even if you have auto-leveling on your fiver you want to start out as close to level as you can so as to not put to much stress on the self-leveling system.

Ok, you have found that the door side of the rig is low and needs to be raised up to bring that side into level.
Now the fun begins.  You will need to put something under the wheels to raise that side of the rig.  You will need what is called an RV Tire Leveling Block,

RV Tire Leveling Block

RV Tire Leveling Block

These blocks interlock so they will stay put if more than one is used and they are designed not to sink into soft soil or blacktop.  Just how many you will need to level up the low side is often just simple trial and error.
I always start with one above ground level under each tire on the low side and go from there.  Let's say that you needed two under each tire on the low side to get level.

Did you remember to pull up on them and not try to back up on them?
Better for the tires if you pull up on the leveling block rather than backing up on them.

Also, did you make sure all tires were centered on the blocks, not on an edge?
The axle of the tire or the hub in the middle of the tire should be centered on the leveling block.
Why? Because it puts less stress on the tires, that really do not like being off the ground in space.

Here is yet another way to level your Rig.  This one is a bit different that the square block used above, this one is a Ramp Style Leveling System and will help you level your rig from any increment between 1/2 inch and 4 inches.  This ramp style will hold up to 30,000 pounds.  If you have two axles then you will require two ramps per side.

Ramp Style Leveling System

The smaller ramp is used to chock the RV from moving once the RV is level.  The ramp with the holes in it, is the adjusting ramp. 

You have checked the levels on both the front and side of the rig right?  So now what?  You need to check that the fridge is level. On way to do that is to use a Torpedo Level

 Torpedo Level

This small 8" level can be used inside the fridge or on the nearest counter next to the fridge to check to be sure that the fridge is level. (Level - not more that five degrees out of level, is very important to the good, safe, and efficient operation of an RV fridge)

You are now level so what is next? Unhooking and stabilizing the rig.
Once you are unhooked you need to put down the corner stabilizer jacks.  Most travel trailers use Scissor Jacks

Scissor Jacks

This type of jack is NOT for leveling your rig.  It is to keep the rig from moving back and forth as you move around inside.  If one of the jacks does not meet the ground you can use one or more of the tire leveling blocks to help stabilize that corner of the rig.  As shown in the above photo a hand crank is the normal method of deploying this type of jack and can be a real pain.  There are two fixes for the hand crank used on these jacks.  One is the Stabilize Scissor Jack Socket for an electric or battery operated drill.

stabilizing Scissor Jack Socket

The second but more expensive way is to motorize RV scissor stabilizing jacks

motorized RV scissor stabilizing jack

This jack is remote controlled and is powered off the rig so it makes the stabilizing fast and easy.

Many of the newer 5th wheels will have will have powered corner jacks and landing jacks.  Some will have auto leveling that will level and stabilize the fiver.  But what happens when you are still getting sea sick from someone walking inside the fifth wheel or travel trailer?
For the 5th wheel, there are several things that can be used and have had success.
First is the Stabilizer Jack

5th Wheel Stabilizer Jack

I use these back at the bumper, where the bumper joins the frame of the fifth wheel.  The use of these has really made a difference in the movement of the trailer.

Next is the expandable wheel chock or X-chock.

X-Chock

This chock does double duty if you use a paddle lock to lock the chock from being removed it will stop someone from being able to steal your RV with-out a lot of work.

Your rig is now level and corner supported but, when someone walks around the inside of the rig it still does the shimmy, shimmy, shake.  Now what?  There are many suggested solutions out there to solve this problem but here is the simplest one that works.  The RV Stabilizer         

RV Stabilizer   

One of these can be added to the rear of the rig to stop side to side motion and or one can be added to the side of the rig to stop the front to back motion.  This looks simple and it is but, it does work.

The X-Chock from above will also work on Travel Trailers to help stop motion and help to prevent theft as well.

OK, now for the guys with money.  If you would like to add remote control automatic power leveling jacks to your TT or 5er, the following is a company that has received good reviews for their lift systems; Big Foot Leveling System

Big Foot Flip Down Leveling Jack for TT

The type of DIY that is required to install this system is not in the scope of this blog.  But this type of wireless remote control system is out there and for those who would like to add automatic power leveling to their rig here is a place to start.

Martha!!! The String On The Blind Broke Again!!!

It happens to most of us,  we grab the shade bar at the bottom of the window blind and pull down to get ready for bed and the darn string running through the blind breaks and while it will go down all the way, there is no possible way that it will go up and stay where you want it in the morning. RATS now what?

RV Window Shade

Above is your typical RV window shade and if you look close you can see the string running through the blind material.  I suppose you could buy a RV Blind String Repair Kit, shown below

RV Pleated Shade First Aid Kit

While the hours spent restringing the blind with your spouse maybe enjoyable, you might want to consider the frustration of not getting it right even after the 5th attempt. 
My suggestion is to replace that blind with something that is a whole lot prettier and will class up the inside of your rig as simple as ABC.

There are two basic RV Blinds.  First the roller blind.  As the name implies it is on a roller and you pull it down to the level you want and the blind will stay there.  The roller blind comes with two blinds on the roller. One is the daytime shade and the other is the night time or black out shade.  The roller can be installed on the outside of the window frame or on the inside of the window frame and is offered in colors for the daytime and night time shade.

Roller Bind Shade

Measuring Instructions:
Determine if the shade will mount outside the window frame onto the wall (Outside mount) or if the shade will be mounted inside the window frame (Inside mount) 

NOTE: Most RV applications are Outside mount.

Outside mount: Measure the width (across) of the area to be covered.Example - Edge of the window to edge of window plus 2" added for additional coverage.

Example: Top of the frame to the bottom of the frame with an additional 2" added for mounting above and below the window.(outside mount)

Inside Mount: Measure the exact opening size and subtract a half inch. Measure the length (Drop) of the area to be covered.

If draperies or valances are already installed be sure your measurement for width allows the shade to fit under the current window treatment.
You can see that you end up with two shades one for daytime and one for night time.  You may find that this is not really what you are looking for and would rather have a true Vinyl 1 Inch Mini Blind.

Vinyl 1 inch mini Blind

Measuring Instructions:
Determine if the blind will mount outside the window frame onto the wall (outside mount) or if the blind will be mounted inside the window frame (inside mount)  

NOTE: Most RV applications are outside mount.

Outside mount: Measure the width (across) of the area to be covered.  
Example - Edge of the window to edge of window plus 2" added for additional coverage.

Example: Top of the frame to  the bottom of the frame with an additional 2" added for mounting above and below the window. (outside mount)

Inside Mount: Measure the exact opening size and subtract a half inch. 
Measure the length (drop) of the area to be covered.

If draperies or valances are already installed be sure your measurement for width allows the blind to fit under the current window treatment.

You can get wooden blinds or different color Vinyl blinds to match or enhance the inside appearance of your rig.  Metal blinds are not recommended because of moisture in the rig.  The edge of the blind tends to rust and the blinds are a bit sharp around kids and fur-babies.
Caution: if you remove blinds from your windows keep all screws that were used to be sure that you do not use a screw that is too long for your RV side walls.

Until next time.
