RV Fridge - Get It Cold & Keep It Cold

Do you find that your RV refrigerator does not keep your food cold enough?  Does your RV fridge have its own unique smell?  Do you know how to chill down a warm RV fridge?
Many of us store our RV in places that do not have electricity for us to keep the fridge plugged in and working all the time or even a few hours before we take off for a fun-filled and safe camping adventure.
So let's talk about the care and feeding of an RV refrigerator.








1.   I hope you do not keep the fridge sealed as tight as a drum during storage.  You need to leave the door cracked open just a bit so that air can move in and out of your fridge. This helps keep the inside of the fridge dry and reduce mold build up.  Did you ever wonder what that slide button on the fridge door is used for? Well to lock the door during travel to be sure but, if you slide the button so that you are locking the fridge door while the door is being held open the slide lock can be used to keep the fridge door from closing during storage. Be sure your fridge is as clean as possible before you close the door on the RV.  Making sure the fridge is clean will help stop the growth of mold inside of the unit.  Also if possible you should use a Naturally Activated Charcoal Odor Absorber like this one; RV Activated Charcoal

RV Activated Charcoal

This little odor eater would hang from a shelf at the back of the fridge to help keep odors out.  You can also use a box of baking soda but that can spill going down the road and make quite a mess. 

2. What can you do to get the fridge colder quicker once you get to the campground or on the way?  You could buy a bag of ice and put it on the top shelf of the fridge next to the silver fins at the back.  You could buy some cheap cold packs That look like this;

Cheap Cold Packs

Freeze them (usually three) and use them in place of the ice.  Very little if any water to clean up.  Or you could get some Zip Lock Heavy Duty Freezer Bags and put ice cubes from your home freezer in them and use them in place of the bought ice. Another idea for an ice pack is to partially fill a strong zip-type sandwich bag with Dawn dishwashing liquid, close and freeze. The liquid soap stays cold much longer and it can be refrozen many times. The frozen Dawn will conform to the place you need an ice pack. Maybe a bit more water to clean up than you would like.
The Nu-Ice Freezer Pack is a  chemical freezer pack capable of maintaining a sub-zero temperature by putting the pack into an insulated environment for up to 96 hours. This is accomplished by first freezing the special pack to initiate the simple chemical reaction within the pack. 

Nu-Ice Freezer Pack

But you could do even better and help the ice or cold pack by adding an RV fridge fan like this one; RV Fridge Fan.

RV Fridge Fan

It uses 2 D cell batteries (be sure to use alkaline type) and will give you 30 days of use before the batteries need to be changed.  It will reduce your fridge cool down time by half. I use one in my TT and it does work. (just be sure to turn it off before storing the rig).

I know some of you are a bit more high tech than a simple battery operated fan inside the fridge and would like something a bit more.  I reference you here; High Tech RV Fridge Fan.

CAUTION:  Do not run your RV Fridge on GAS while going down the road.  Guys this is very dangerous for a lot of reasons and not recommended by anyone in the know that I have talked to.   I am sure someone will tell you that they have done it for years with no problems.  But it only takes one time, of a fire or explosion or both.

3. What else could you do to help your RV fridge?  You could put a fan on the backside of the fridge inside the outside fridge compartment.  I am talking about the outside compartment in the back of the fridge.  There are several types of this kind of fan.  One type uses a thermostat to sense when there is too much heat, inside the outside compartment, thus slowing down cooling, and turns on the fan.  Or there is the DIY system that uses a 12-volt computer fan that comes on whenever power is turned on to the rig (this is what I use).  Let's look at them both, first the thermostat controlled fridge compartment fan; RV Fridge Outside Compartment Fan

 There is some DIY here as well but a lot less than the system that I use.  Follow the link and read some of the user comments to better understand how this system works.

 RV Fridge Outside Compartment Fan

Next, let's take a look at the one I used; 12 Volt Computer Fan

This is a completely DIY project so please remember that.  I found a convenient place on the inside of the outside refrigerator compartment's grated grill cover and mounted the fan with some zip ties.  I ran the power wire from the fan to the rigs 12-volt power line, that I found inside the refrigerator compartment.  My 12-volt lines were the same color as the fan's wiring. The fan blows air across the fins on the outside of the fridge located inside the fridge compartment.  The power draw is so small I did not worry about it and the fan runs whenever the rigs 12-volt system is on.  The fan is designed to be used in a computer so is whisper quiet. Boy does it work.

4. So we have the fridge getting cold but how cold is it and when can I put in some food?  Well if you do not have a thermometer to measure the temperature then how do you know?  There are two kinds of thermometers one is digital and one is analog.  Let's look at them both.

Digital RV Thermometer Digital RV Thermometer

Digital RV Thermometer

The unit has two sensors one for the freezer and one for the fridge.  The unit runs off batteries and can tell you at a glance from the outside of the refrigerator unit what is going on inside and when your unit is cold enough for food.

Analog RV Thermometer; Analog RV Thermometer

 Analog RV Thermometer

This simple unit hangs from one of the shelves in the fridge and tells you when it is safe to put in your food. The negative thing is that you have to open the fridge to tell if it is ready, letting in more hot air and letting the cold air out.  I am saving for the digital version.

Well, we've got your RV refrigerator humming along but, it is time to go home and park the rig until the next time.

How can you get it cleaned out and dried out fast?  One of these guys should help; Inexpensive Hair Dryer

Inexpensive Hair Dryer

Because I do not dry camp I have the power needed to use this, to dry out the fridge and freezer fast and get going home. Darn, the ice cream is going to melt again.









Until next time.

Do RVers Really Need A Power Management System?

I see that question all the time on Facebook and most of the Blogs that I read.  For the simple, easy, straightforward answer, YES you do.  There are so many factors involved here that I can not possibly cover them all in a single post but, I would like to cover the basics so that you can better understand why you need a Power Management system of some kind.





1. You need to know what the AC (Shore Power) voltage is inside your rig.  This is the power that indirectly powers lights, water heater, microwave, furnace, charger for the 12-volt battery system, etc.  If the voltage gets below 102 volts and should stay there for a few minutes it would be possible to sustain approximately $1200 of damage or more.

So what do you need?  You will need an AC Line Voltage Monitor.  The unit shown below is plugged into an AC wall outlet that you can see and will monitor what the line voltage is.  If it should go below 105 volts you need to unplug your rig from the outside power pedestal until the voltage goes back to normal.

AC Line Voltage Monitor

So how do you know when the outside power pedestal is back to normal.  You plug the Voltage Monitor into the 125 volts two pin socket in the power pedestal and see what the monitor reads.  It should read 110 volts or higher up to 125 volts.  The same caution goes for overvoltage.  You should unplug the rig from the power pedestal if your Voltage Monitor begins to read over 122 Volts.  Plug the Voltage Monitor into the power pedestal and watch for the voltage to drop to below 122 Volts.
Could this monitoring of the voltage be done for less money?  Yes, by using a cheap Digital Volt Meter  pictured below;

 Digital Volt Meter  

Harbor Freight often offers a cheap digital voltmeter for free, with coupon.  Watch their ads and take advantage of the offer.  You could plug the test leads that come with the meter into the meter and then the other ends of the test leads into the slots on the AC wall socket. (Caution do not leave unattended) Or you could make up a cord from a 6-foot extension cord and the test leads that come with the meter.  See below for an example.

AC Cord With Test Meter Leads

2. Next is  The Polarity Tester.  This is used to be sure that the Neutral wire of the power line is not reversed with the positive lead of the power line.  If that were to happen you could have what is called a hot-skin condition.  Meaning that if you had an aluminum skinned rig you could receive quite a shock from your rig.

 The Polarity Tester

The Polarity Tester can also tell you if the Earth Ground (the bare copper wire) is hooked up properly.  
The Earth Ground is a separate conductor which may seem to be doing nothing but, is, in fact, a protective wire. It is there, ready to take the current away to earth ground, from the body or frame of the electrical device it is connected to, makes contact with any "hot" wire. [the 120 volts mains power is carried in two current carrying conductors called "hot" and "neutral".] 
So, IF one of the "hot" conductors should contact the metal frame of the rig, or housing of an appliance, perhaps because the appliance got damaged by being dropped from a table, or similar accident,  the third wire which is the earth ground wire, which runs directly from the housing to the grounding [or earth ground bus] in the fuse or breaker panel, will in effect cause a short circuit which should blow the fuse or trip the breaker. 
This third wire also guarantees a current path back to the electrical panel where the fuse or circuit breaker protecting that circuit is located, in the event that the hot wire should come in contact with the rig's frame, but the neutral conductor should happen to have been cut or damage and become disconnected, or open. 
The idea is to guarantee that if a part of the rig, device or appliance should become "hot," which could be fatal to anyone who then came into contact with it. That the earth ground would trip/open the circuit protection device [fuse or breaker], and turn off the flow of AC current. 

To help further in checking for unwanted or wanted electricity a good investment is the, Voltage Sensor which is shown below;

 Voltage Sensor

With this probe, you do not need to touch the power line to tell if there is voltage present.  You can use this probe to find power lines behind the wall or under the floor of the Rig as well as the towing vehicle.

3.  Often times you want to know or need to know how much power something uses, especially if you keep popping a breaker or the power pedestal. The solution is Kill-A-Watt .  The unit shown below can be used to show how much power an appliance, tool or piece of electronics is using.

 Kill-A-Watt

4. Next, let's look at surge protectors for the various pieces of equipment in your Rig.  Surge Protectors protect only what is plugged into them and only for over-voltage surges.  Surge Protectors do not protect for under voltage or high voltages.  Shown below is a pair of good simple surge protectors;

Surge Protectors

There are Appliance Surge Protectors made just for appliances like microwave and coffee makers

 Appliance Surge Protectors

AC refrigerators, freezers. 

Refrigerator/Freezer Surge Protector

These special surge protectors offer extra features like audible alarms, flashing lights, displays, etc and are to be used with just the items listed on the packaging for the one you would buy.

5.  Next is a group of power management items that will protect your entire Rig not just one item or several items in it. First is the Portable Power Management System This type of system looks at High and Low voltage protection, a time delay for air conditioning compressor startup, 3-mode surge protection, reverse polarity protection, open neutral protection, open ground protection, AC frequency protection accidental 220 Volt protection. Includes an Integrated information panel, previous error code display is weather resistant and has a built-in locking bracket so it can be chained to the power pedestal at the campground to prevent theft.  The only thing this unit cannot do is flush the black water tank.  The miracle unit we are talking about is shown below.

30 Amp RV Surge Protector

These portable units come in two sizes the one above 30 amp and the one shown below 50 amp.

50 Amp RV Surge Protector

Let's say you were involved in a lightning-caused power surge at a campground.  It is estimated you would suffer approximately $3000 to $5000 worth of damage to the electrical system of your Rig along with the things plugged into it.  The features of the 50 amp unit are the same as the 30 amp unit.
Ah, but there is more!  What happens if you do not want something portable but something more permanent in the Rig? Then you have the permanently installed units which are called Fixed Power Management Systems  These units are not really a DIY type of item but, they can be installed by the DIYer if care is taken during the installation.  The 30 amp model is shown below;

 30 Amp Fixed Power Management Systems

There is also a 50 amp version of the same unit as above and can be found here;  50 Amp Fixed Power Management Systems .  The features of both units are the same and are,  high and low voltage protection, time delay for air conditioning compressor start-up, 3 mode surge protection, surge trip indicator, reverse polarity protection, open neutral protection, open ground protection, AC frequency protection. Accidental 220V protection, with remote information display panel, and unit bypass switch.  Unfortunately, this unit also does not dump the black tank.

I hope that you now have come to the conclusion that some type of power management is needed to protect your Rig, its contents and YOU!

Basic Tools For The RVer

What tools do you need to have when RVing?  If you ask 10 RVers you will get 10 answers.  That's because we all seem to run into problems with our RV that is a bit different from the next RVer and the tools to fix the problem that arose is slightly different. But there are some basic tools of the trade, so let's talk about those.






You will find that you will need something to put whatever tools you decide to carry into something that is strong but light.  Tools have weight and it does not take too many until you have added measurable weight to your rig. So here is a toolbox that works.Simple Tool Box

Now that we have a toolbox, lets see what needs to be in it.

A screwdriver Multi Screwdriver

I chose one like above because it cut down on weight and space in my tool box.  If you rather, you could buy two flat blades (one large, one small) and two Phillips screwdrivers a #2 and #1 or an  additional size of your choice.
You will need a special set of screwdrivers for use with those pesky square headed screws that are used on the inside and the outside of the rig. These special square screwdrivers are shown below.

square screw drivers

 A set of basic pliers is next.  You will need several types.  Here is an example Basic Pliers

Basic Pliers

You will also need several advanced pliers, such as the ones shown below.

Slip Joint Pliers

Vice-Grip Pliers

You will need and use all the above pliers.  It is just a matter of time.  Next we move on to crescent wrenches.

#10 inch Crescent Wrench (10 inch Crescent Wrench)

Now for the special stuff.  This is stuff you need but may not use monthly.  I use this stuff as needed.  The first is the torque wrench.  This is used to check the lug nuts on the tires of the rig to make sure they are tighten to factory specifications. I use this before each trip to check the lug nuts on the tires.  I have found that some of the wheel lug nuts do change. 

Torque Wrench

3/8 inch Extension Bar Kit

3/8 inch Extension Bar Kit

The extension bar kit is used to get the torque wrench outside of the tire rim for a safer tightening of the lug nuts that hold the tires.  You will also need a drive socket that fits your tires lug nuts and is made for a  3/8" drive.

If you have a Suburban water heater you will also need a breaker bar shown below, to remove the anode to check the anode as well as to replace the anode if needed.

3/8" Breaker Bar Wrench

You will also need a socket that fits the anode, along with the white plumber's tape

 to prevent water leaking around the threads.  I have always carried a spare Anode Rod just in case, you just never know when you will need one.  Be sure to change the rod yearly.

Of course a hammer is also a tool that should be carried

To see into those dark areas around the RV you will need a small but powerful flashlight.

One tool that I have that I really like is not really a tool but my multimeter.  I can check to see if there is voltage what kind and how much.  I can check for open and shorted wires as well as other things.  I highly recommend one for your toolkit. 

Multimeter

Another tester that is handy and some people think it should be a mandatory basic tool is the AC voltage monitor.  This shows what the park voltage is at any given time, (low voltage can damage your RV electrical system and electronics) and shows if the power pedestal is wired correctly if plugged into the pedestal before plugging in the RV.  Note: "You may have to get a Short jumper [Dog Bone] from 30 or 50 amps to standard AC wall socket to test the pedestal."  Meter is shown below.

AC Power Monitor

The following is the tool I would not be without.  The multi-tool.  I carry this tool on my belt and I even bought the expansion kit for it.  You just never know when you need a screwdriver or pliers to tighten or loosen something.

Multi-Tool

Multi-Tool

I know someone will say, this is not all you need and will give me a list of stuff as long as my arm.  Things like gorilla tape, super glue, black electrical tape, clear and white silicone caulk.  I agree they are important and should be carried, but as I said earlier. This is the basic list and like American Express "I never go RVing with-out them"

Until next time.

Keep Track Of Your Tire Pressure And Temperature

I read all the time that one of the biggest fears people have when RVing is a blown tire and the massive amount of damage that it can cause.  But I rarely read about a Fulltimer or a Newbie adding or adjusting a Tire Pressure Monitoring System (TPMS).  Why?  I doubt that every RV sold comes with a tire monitoring system. I just got back from one of the big RV shows and not one 5th wheel that I looked at came with a TPMS nor did a single salesman recommend a tire monitoring system during the sales presentation.  I also read that more than 60% of the RVs on the road today are overloaded or worse that the tire pressure on the RV is below the manufacturer's recommended tire pressure.  To make it worse [if that is possible] many of the  RVs going down the highway, are going at  70 mph or higher. Even though the RV's tires are marked not to exceed 65 mph.  As we get our RVs ready for another season of camping, let's look at what we need to do to be safer going down the road and monitoring our tires.  

1. 

You need to check the tire pressure when the tire is still cold. 

It has been shown, by an  infrared thermometer, that after only 10 minutes of Summer Sun, that the temperature of RV tires have risen above COLD and should not be measured for pressure and thought to be cold.  After you have driven 1 mile the RV tires are not considered cold and should not be tested for pressure as being cold. 

2.
When you stop for gas or a bathroom break, you should do a tire check of the RV as well as the tow vehicle. My daughter was checking the tow vehicle for me and found a large cut in the sidewall of the truck tire.  We were able to get the tire replaced before the large accident occurred.  I did not even remember hitting or running over anything on the highway.

3.
Before starting out on the RVing trip be sure to carefully look at the tread, and the side walls both on the front and the back of the tire.  Most RV tire experts agree that if your RV tires are more than five years old from the date of manufacture [shown in a code on the tire] you should replace them. 

4.
Most tire failures occur when the side wall of the tire is under inflated or rots out from the inside where you can not see. Remember you are riding on air, the tire just keeps the air captured and held in place.  You can thank Mr. Sun for sidewall failure in some cases.  Most tires have a Mr. Sun inhibitor built-in but when a tire sits and sits the inhibitor does not get moved to the outside of the tire by the tire going round and round.  Now you see why you need wheel covers right? Trailer Wheel Covers   for less than $25. 

Trailer Wheel Covers 

OK, I have exposed you to some of the basic safety things you need to do, now let's look at those Tire Pressure Monitoring Systems.
A good system for monitoring your tire pressure as well as the tire temperature is the  Wireless Tire Pressure Monitoring System .

Wireless Tire Pressure Monitoring System

The system will tell you of an overheated tire, in most cases before it blows, and of course tell you of low pressure in any monitored tire, even the spare, in real time. 

• Monitors up to 22 wheels (0-232 psi)
•  Quickly reacts to abnormal pressure or temperature
• Waterproof & Dustproof sensors; 
• Customizable Tire Pressure Monitoring Criteria
• Sensor Alarm system included; Locking Ring to Guard Against Theft
• For use in RVs, SUVs, Caravans, Trucks, & Passenger cars

RV Flow-Through 6 Tire Sensor - Tire Pressure  Monitoring System (TPMS)

RV Flow-Through 6 Tire Sensor - Tire Pressure Monitoring System (TPMS)

• The flow-through sensor with replaceable battery can be secured to prevent loss or theft
• Portable monitor has rechargeable battery and monitors tire pressure 0-199 PSI & temperature
• Monitor tires 24/7: low/high pressure, high temperature, and slow leaks.
• Monitor warning thresholds are user adjustable; low-pressure alert level is per axle adjustable.
• Tire sensor signals have excellent range and not require signal booster for most vehicles

As a lower cost alternative, you can use a screw-on tire pressure indicator, such as Quick-Pressure-PSI-50-Monitor, which at a glance can tell you that you may have a problem [use only if your tires are supposed to have 50 lbs of air when cold. Other pressures are available]  and the traditional pencil like gauge, such as Pencil-Pressure Gage .  

Quick-Pressure-PSI-50-Monitor

Pencil-Pressure Gage 

A low-cost way to check the tire and the tire hub temperatures is to use a non-contact  Infrared temperature gun.  Such as the HDE Non-Contact Infrared IR Temperature Gun Digital Thermometer

HDE Non-Contact Infrared IR Temperature Gun Digital Thermometer

As you stop during your travels you can check the tire temperature and hub of each tire.  They should be with-in a few degrees of each other.  If you find a tire or hub that is very much higher than the rest you should take action to find out why before you proceed.

The first thing you should do is to check the air pressure of the tire that is over heating.  I know that you have been traveling awhile but the pressure in the HOT tire should be with-in a few pounds of the rest of the tires on the rig.  You might want to consider a digital tire pressure gauge such as the NorthONE Digital Tire Pressure Gauge.

NorthONE Digital Tire Pressure Gauge

Just be sure that the gauge you buy can read pressures above those that your tire is supposed to have in it.

To protect the tires in storage from Mr. Sun and any other nasties that come along.  You can also use an RV tire protective spray which is applied, as directed, to the tire side wall that is exposed to the sun.
I have used RV Tire Protection Spray with good luck.  This spray is not designed to make the tire side wall shinier, it is not a decorative spray, but something that is designed to put back into the surface of the rubber what Mr Sun is taking out.

RV Tire Protection Spray

Also note, that if you are going to store the RV for an extended period of time you should protect the tread of the tire from the surface that the tires are sitting on.  Nasty things can leach out of your tires into the blacktop or concrete that your RV sits on while being stored. Or from the blacktop or concrete into your tires during storage.  You can use an  Office Chair Carpet Protector 

 Office Chair Carpet Protector 

as a way to protect your tires during storage.  It is an inexpensive solution to tire protection during storage.

I hope this better explains why it is important to know what is going on with your tires and also helps with the fear factor.

Until next time.
