7 Things you need to know before you make
Campground Reservations
What's that Rotten Egg Odor in the Hot Water?
Air Spring Kits
can be very helpful in leveling and stabilizing a vehicle.
Driving For Fuel Economy
For years curiosity has
kept me searching for the most economical way to drive.
RV Satellite
Satellite television is a good choice for an RV. Satellite service
is very similar to a home system. The primary difference is in the
antenna (dish).
RV Generators
RV generators are set up
with a cooling system, air intake, and exhaust system
Top 10 Towables
On the new 2006 list
L.P. Safety
Liquid propane is referred to as L.P. L.P.
is a fuel used in RV’s to provide a flame for items such as stoves,
heat absorption refrigerators, barbeque grills, hot water heaters,
and furnaces.
RV Water Systems
RV’s have 2 water systems,
city water and onboard (potable) water.
RV Holding Tank Use
Holding tanks are the built in tanks that
hold any waste coming from your RV. Typically, there are a series of
tanks.
Understanding Your RV Battery
The batteries in your RV are the “heart” of the electrical system.
Good batteries with the proper charge are important for many
reasons.
Season Prep - Spring
Preparing Your RV for Use
You need to prepare your RV for the first use of the season.
Here is a list of important items and systems to inspect and test.
1. Outside: One of the biggest problems we see with RV’s
is water leaks.

Basic RV Power
RV’s have 3 power
sources. All 3 are necessary in certain circumstances.
“Coach” refers to the camper portion of the RV. “Chassis” refers to
the truck portion of the RV.
1. 12 volt dc power: There is a “coach” battery or series of
batteries. This battery supplies
power for the lights, water pump, hot water heater ignition,

RV Refrigerator
An RV refrigerator is quite different than a conventional
refrigerator.
RV refrigerators are a heat absorption type instead of a
compressor type.
They almost always feature 2 way operation. 1 way is 120 volt ac
electricity and 1 way is L.P. gas.

RV Refrigerator Repair
There are several areas of an RV absorption type refrigerator that
can cause failures. Most common failures are cooling units and
electrical problems.
The cooling unit is the part of the RV refrigerator that contains
the chemical. If you smell ammonia in the vicinity of the
refrigerator, the cooling unit is leaking. That is considered a
major malfunction.

Dinghy Towing Series
Tow Dolly
I will start with tow dollies. A tow dolly is a 2 wheel device
with a platform and ramps that attaches
to your RV’s tow hitch. A dolly requires attachment to your RV,
driving your tow vehicle up the ramps
to the platform, latching the dolly so the ramps are in a locked
position, and strapping the tires to secure
the vehicle to the dolly.
Towing 4 Wheels Down
Towing 4 wheels down is the preferred towing method.
In my opinion any vehicle that does not require an additional
driveline device is recommended.
We have been installing tow systems for nearly 20 years. In the
beginning the choices were very limited.
If you wanted to tow 4 wheels down,
the choice was either a Honda or something with a manual
transmission. Now there are many more choices.
There are also some driveline devices that can be added to make
nearly any vehicle towable.
Lights & Wiring
There are several options for rear lights while towing. Light bars
and separate lights are one method.
Using the towed vehicles existing lights is another method.
A light bar can be used if towing for a limited number of times.
There is little labor and time involved in set up.
Since most RV’s have a wiring connector already in place, you can
simply run an
extension along the tow bar and back to the lights.
Tail Lights
Now for the difficult part:
tail lights.
Tail lights are difficult for several reasons. Isolating the circuit
from feedback using a diode
will require splicing or running new wires to several locations.
Typically installing a diode at one rear light fixture will only
power 1 light. There are some options to operate both lights.
You can rewire the rear light from the other side and splice in to
that diode, or you can use 2 diodes.
Braking
Units
There are several brake boxes
available for your towed vehicle. Blue Ox, Roadmaster and Brake
Buddy are 3 examples.
A brake box is a simple to use device that sits on the front
driver’s floor of the vehicle.
They are powered from a 12 volt outlet or can be hard wired if an
outlet is inconvenient or doesn’t exist.
These boxes operate from an inertia mechanism..
Air
Brakes
There are several
braking units that will work with coach air brakes.
This article explains Blue Ox’s BrakeSafe and Roadmaster BrakeMaster
units.
These systems are quite simple and work very well, with the braking
unit operating in tandem with the coach brakes.
M&G
Braking Unit
M&G braking is a good choice for coaches with air brakes.
The advantage M&G has over other braking units is
