Braking Distances

I am sitting here drinking my morning coffee and thinking about what the subject should be for this weeks article.  As you know I have posted a lot of things on here about inspecting and lately about the maintenance.  But today a post on the web got me thinking that most of us have no idea how to safely drive our rigs.  Face it, we spend most of our time in a car or light truck and then when we want to go camping, we just behind the wheel and off we go.  We have gone from a 4 wheel 2000 lbs vehicle to as many wheels as an 18 wheeler with weights approaching 40,000 and maybe more.  Some of these are air brake equipped just like the big rigs.  Then we hit the road and maintain speed with everyone else and the following distances just like a car.

So I started to do some research on braking distance in an RV.  First some perspective.  A car traveling at 60 MPH takes about 200 ft to stop.  That is according to a couple of posts  I found the average big rig takes about 40 percent longer to stop than a car.  So the Class A’s should take about 280 feet to stop.  This does not include the reaction time which is another 1 to 1.5 secs.  At 60 MPH that is up to another 135 feet or more than a football field.  All totaled the car will stop in about the football field from the time the driver see the problem until the vehicle is stopped where as the RV will take almost 1.4 football fields to stop.

So basically, you need to slow down and increase the distance between you and the vehicle in front.  If someone pulls in front of you, remember that you still need over a football field to stop and it will take 135 feet before your foot is even on the brake to think about stopping.

Camping is not about the race to get there, it is about relaxing and enjoying life.  Start the camping trip when you leave home and relax and enjoy the trip.

Annual Safety Briefing

It is that time of year again when we will be pulling out the RV and hitting the road.  So it is time for your annual safety briefing as well.  I want to bring up a subject that I feel is so important.  Your RV Weight.  These homes on wheels have a limited amount of weight that the RV can safely handle.  It is called the  Gross Vehicle Weight Rating or GVWR.  This is the maximum you can safely put on the wheels and tongue of the RV.  It is also the maximum LEGAL weight you can have.  If you exceed this weight and you have an accident, you can be held accountable for the accident, even though you were not at fault, because your vehicle had exceeded its weight limit.  So how do you determine your weight?  Go to a truck stop that has a CAT scale, spend $11 or $12 dollars and have the RV weighed.  Compare the value you will be given to the RV sticker that shows the GVWR.  If you are overweight, you need to remove stuff from the rig until you are back under the GVWR.

Overweight is the leading cause for RV accidents.  When you are overweight you stress the tires and they blow out.  In addition, tires pressure needs to be increased as the weight increases.  Failure to have the proper pressure for the weight they are carrying will cause the sidewalls to bulge and also leads to premature failure of the tires (blow out) which causes loss of control, damage to the RV and possible loss of life.

When you have your rig weighed you will be given a sheet of paper that shows the weight on each wheel.  This is very important information as it determines the pressure for that tire.

Let me show you an example.  I have Good Year tires on our Class A.  According to the weigh ticket my front axle weighs 8960 lbs.  Divide that by two and each tire is carrying about 4,500 lbs.  I rounded up for safety.  At that weight the tire pressure according to Good Year should be 90 PSI.  My rear wheels are dual tires.  My rear axle weight is 16,180.  Divided by 4 is 4,050.  Again according to Good Year, my tire pressure for the rear wheels should be 85 PSI.  So you can see that the tire pressures are different for the front and back.  Since these tires can be pressurized to 120 PSI, I keep the all at 95-100 PSI most of the time.

How often should you weigh the RV?  If you are pretty constant with how you travel, once should be enough I would guess.  But if your load changes, or you start carrying water or propane when you didn’t use to then weigh your rig again.  If in doubt, weigh it again.  It is better safe than sorry.  Remember SAFETY IS YOUR RESPONSIBILITY.

 

Water Heater Maintenance

There are currently 4 different water heater types you might find in an RV.  The two most common are from Suburban and Atwood.  New to the RV world are the On Demand Water Heaters and in higher end motor homes you might find a system that provides both heat and hot water called Aqua Hot.

Maintenance on Atwood heaters is pretty simple.  About once a year usually when you winterize, you want to clean out the water heater holding tank really well.  The best way is to take out the drain plug.  Caution here:  Make sure the tank is cool and that the power and propane are off to the water heater.  You do not want the heater to begin trying to heat the water when the tank is empty.

Once you have removed the drain plug, flush the tank with plenty of water to remove the loose calcium.  Next you will need some white vinegar.  About a gallon for the 10 gallon water heater.  This is a good time to also clean the water holding tank on the RV.   Perform the same basic steps, drain the water in the holding tank, flush to remove the calcium and then using a ration of 1:10 (vinegar to water) fill the holding tank.  If you are doing the holding tank at the same time it will make it easier to do the how water system.  Fill the holding tank with vinegar and then pump it into the hot water tank (make sure you put the plug in the water heater before filling).

Once the vinegar and water are in the tank(s) let it sit for a couple of days.  The acid in the vinegar will loosen the calcium.

After a couple of days, drain and flush the system(s).  If you are working on a Suburban Hot Water system, now is a good time to replace the Anode Rod.

Then Anode rod is to protect the insides of the steel tanks used in Suburban water heaters from rusting due to chemical reactions in the water.  The Anode rod is made of a mixture of Zinc, Magnesium and Aluminum.  Which reacts quicker to the chemicals in water that can rust the steel tank.  Failure to replace the anode rod as needed results in the water tank rusting out and having to replace it sooner than needed otherwise.

That is it for the normal water heaters found in most RVs.  I am still researching the maintenance of on demand and Aqua Hot systems.  Those will be covered in the next article.

 

 

Delamination – What is it?

If you read Facebook RV Groups at all or any RV Forums you will see many articles or questions about delamination.  Many of us know little about the issue but maybe would like to know more or you need to know how to fix it.

I recently chatted with Andrew Newton of Composet Products L.L.C.  Composet offers a product for fixing delamination.  I asked Andrew about delamination and what causes it.  Here are some of the questions and his responses.

What is delamination?

Many RV walls are a “composite”, meaning different materials are bonded together in layers. Typically, a thin fiberglass sheet forms the outer layer, followed by luan plywood*, Styrofoam, and an inside panel. Framing elements are also incorporated into the wall. The materials are glued together creating a composite structure. Delamination occurs when the bond between one or more layers fails. This happens in isolated segments, or throughout the entire panel.

Why does delamination occur?

In many cases a leak forms allowing water into the wall. Typically this happens at windows, vents, lights, roof lines, etc., where caulking is sometimes the only barrier to outside elements. Age, workmanship, vibration, maintenance, and environmental exposure are factors. In my opinion, most delamination occurs when the water breaks down the glue used in the manufacture of the luan plywood and results in the plies separating.

How can you spot delamination?

Look at the wall from an angle and check for bulges. Most sidewalls are not perfectly flat, so this can be tricky, however, the bulge will be worse when the wall is in direct sunlight due to the de-bonded materials expanding at different rates. Next, tap lightly on the wall with a plastic screwdriver handle, solid areas and delaminated areas sound different.

How is delamination fixed?

The most comprehensive way to fix delamination is by replacing the entire wall, requiring major reconstruction. Sometimes sections of walls are cut out, with a seam or joint created where the patch panel is installed. I have seen cases where the layers are re-bonded one at a time. Another process, developed by our company, Composet Products L.L.C., utilizes an injection process to saturate the affected area with a proprietary catalyzed composite bonding adhesive, followed by clamping. Every situation is different with your expectations and budget guiding the definition of a successful repair.

*Luan or Lauan plywood is made from the wood of the Lauan tree from the South Pacific Rim. Lauan wood is usually referred to a medium-grade Philippine mahogany. This produces a very lightweight wood that is softer than most softwood plywood. The surface finish of Luan plywood is very smooth, mostly without defects. The small defects that are found are filled and sanded smooth with the surface. However, because of these defects, Luan is generally only used for projects that will be painted.

Thickness

Luan is typically only manufactured in 1/4 inch thickness, although you can find it as thin as 1/8 inch at times.

Next week, I will go over the process of repairing delamination using the products that Andrew’s company offers.  It is an inexpensive kit that fixes a very expensive repair.

Solar Cells and RVs

I did a little research into Solar Cells and RVing.  This is a non bias review of the issue.  I am not involved with sales, installation, boondocking, dry camping, Green Peace or any other environmental cause.  I am looking at it from a purely financial and beneficial stand point.

Let start with the size in amps that would be needed for an off the grid RV.  If you are frugal with your electric use, leaving the lights off, using propane for heating water and air, limiting your tv and computer time you can probably get by with about 20-30 AMP/H.  You have to remember that you have a lot of equipment in the RV that uses electricity even if you aren’t.  You smoke, CO2 and Propane detectors, the converter/inverter, the refrigerator (even on gas uses 12 VDC) and water heater all use DC all the time.  Then you have fans, lights, electronics that also use AC all of the time.  So just to keep the system running I figure you will need from 500 to 600 Watts. Then on top of that you have your entertainment and living wattage. So figure you will need from 800-1000 watts of consistent solar power to meet your needs as a minimum. Now solar panels are only about 6% effiecent.  That means that to create that kind of power you will need 15 sq yards of space on the roof or about 6-8 panels, depending on the part of the country and the weather.

Equipment needed is the next area.  You need the panels, charge controller, batteries, converter/inverter, monitoring unit, wiring, mounting hardware and the available weight on the RV.  So lets talk about weight first.  The solar panels are going to weight around 40-50 lbs each with hardware and wiring.  The batteries will weigh about 50 lbs each.  You will probably have 4-8 6 volt batteries.  The controler will weigh in at about 15 lbs. The monitor is 5 lbs. Total added weight to the RV for 8 panels would be about 900 lbs.

Cost for all of this is the real kicker.  There are all kinds of prices out there from $200 set up to $6000 or more.  Basically you will get what you pay for.  A trickle charger setup will not work for boondocking. It is designed to kept the battery charged when not in use.  Basically the first panel will run from $800-$1000 plus installation. Each additional panel will be from $600-$750.  So you can see that an 8 panel full time off the grid system will probably cost you from $5000 to $6250.

All of this assumes you are living in the desert with no bad weather, that you always have a clear shot of the southern sky and that the panels are mounted to be able to track the sun during most of the day. Which means you will also need a supplemental energy source as well, IE a generator.

I don’t know how long you plan on boondocking, but for the heck of it lets do some math.  First off the resale value of a used solar system is non-exsistent. So you won’t recover any of your investment that way.  The good news is it should last 20-25 years.  The added holes in your roof will probably mean more maintenance and sealant over the years and will affect the resale value of your rig.  So unless the buyer is also looking to boondock and wants to take the solar system as well, you will lose money on the RV when you trade it in.
Solar vs Generator?  There is no doubt that solar over the long haul will reduce your energy expenses, but by how much?  A generator run about a gallon of fuel an hour.  If you are using gas that means it cost about $3 an hour to run and you will run it about 3-4 hours a day to keep the batteries charged, so $12 a day.  So for the first 416 days or so of boondocking you it will be cheaper to use a generator than installing a $5000 solar system in perfect sunlight.  Call it two years before you will see a benefit of using solar over generator as a full time boondocker.  If you hook up at a campground at all, then the time extends out even more.

Since we plan on only boondocking a week or so a year once we head West, it was pretty easy for me to see that this wasn’t worth it.  You need to decide if it is for you.

Tip of the Day … Exterior Inspection Part 3 – Undercarriage

Tip of the Day … Exterior Inspection Part 3 – Undercarriage. This is the final part of the external inspection. Lets start with the rock guards. These are the plastic pieces around the tires. Are they there and in good condition?

Although not actually under the carriage, check all of the lights. These include the brakes, running lights, backup lights, exterior lights and entrance lights. Are all bulbs working? Some of the new lights are LED and made up of multiple sets of LED. If all are lit then good, if the majority are lit, then I would pass it with a note. If less than half are missing then I would require them to be replaced.

If the RV has a trailer hitch, you want to make sure that it is working and has all the parts are there. See if there is documentation or a sticker on the capacity of the hitch. You want to make sure that you do not exceed the hitch rating regardless of the capabilities of the unit.

Check the jacks/leveler for operation. Make sure they perform as required. Manual jacks are not met to raise or lower the unit only to stabilize or reduce the movement of the unit when extended. Hydraulic jacks found on motor homes will literally raise the unit off the tires, but this is not recommended for long term use. For safety reasons, do not used levelers to change tires. Prior to operating any hydraulic unit, make sure that the pump has enough oil/fluid.

Tip of the Day … Exterior Inspection Part 2 – Side Walls

Tip of the Day … Exterior Inspection Part 2 – Side Walls. This is an area where most people make a cursory inspection.  Things to look for here that are major areas of concern will be delamination.  Delamination is caused by water getting between the outside material and the wood backing, causing the materials to separate.  You will also want to look for damage due to accidents.  Besides the side walls you will want to check the storage doors.  Open all of the doors and check for rust, damage, operation etc.

Entry Step and Door are next.  You want to make sure that the steps operator properly.  If they are electric, there will be a lock out switch somewhere inside the unit.  Test to make sure that it operates properly, preventing the stairs from extending.  Check for excessive signs of rust. Check to make sure the stairs retract fully.

For the door, make sure that the keys work.  Check around the window for any signs of leaking.

Check under the slide outs.  Here you are looking for damage, both by water and accidents.  Check for excessive rust. If the slide has a topper (awning), check the material and connections.  Check for rusty or corroded screws and bolts.  With a ladder, check the top of all the windows.  See if they need caulking and for water damage.

Check all the appliance doors. These include the hot water heater, refrigerator and heaters.  Make sure they all operate as required.

Check all of the awnings.  Look for pin holes in the awning material.  Operate the awning(s) to make sure it(they) retract(s) completely.  Check that the metal components are in good shape and work normally.

Finally check the seals.  There are two seals for each slide.  One on the lip of the slide, which is the one to check while doing the exterior inspection.  This seal is used to seal the slide when it is retracted.  Its purpose is to keep water out of the unit when driving down the road.  We will check this again, prior to the road trip.
