AC (ELECTRICITY)
Alternating current also known as shoreline
power. For purposes of this manual, it refers
to 120 volts AC (abbreviated 120 VAC).
AMP
Short for ampere, the electric current unit
of measure. RV sites with electric hookup
will specify the maximum amps supported,
which generally come in units of 20, 30, or
50 amps. The RV power connector must
match the various plugs of the site amp
rating.
ANODE ROD
Water heater component that draws
corrosion-causing products away from the
metal tank inside the heater. Aluminum
water heater tanks feature a layer of anode
metal and therefore don't require an anode
rod.
AUXILIARY BATTERY
Extra RV battery kept on board to power 12
volts DC equipment.
AXLE RATIO
The number of revolutions needed to turn
the axle once. Higher ratios mean higher
torque and more towing power.
AWNING
A roof-like structure made of canvas or
synthetic materials which extends from
the RV body to provide shade. Awnings
are generally placed over entrances. Some
extend and stow manually while others are
operated electrically.

backing in an RV as opposed to pulling

the driver a better view of what's behind them,
when reversing or when towing on the road.
BASEMENT
Storage compartments below the floor of an
RV that can be accessed from outside.
BACKFLOW CHECK VALVE
A device designed to allow fluids to flow in
only one direction.

emptied at a dumping station.

and generators, and water comes from the
fresh water holding tank.

BRITISH THERMAL UNIT (BTU)
Measures the amount of energy needed to
increase the temperature of one pound of
water by one degree Fahrenheit. Used as a
rating for RV air conditioners and furnaces.
BUMPER-MOUNT HITCH
Type of ball hitch that is either mounted or
attached to the bumper of the tow vehicle.
Can have limited RV applications.
BYPASS VALVE

water heater.
CAB-OVER/OVER-CAB
Any portion of an RV that extends above the
top of the tow vehicle's cab. Usually includes
a sleeping area referred to as over-cab
sleeping.
CAMBER (WHEEL ALIGNMENT)
The degree to which each wheel is off of
vertical. Positive camber refers to when the
tops of the wheels are farther apart than the
bottoms. Heavier loads can create negative
camber, which makes the bottoms of the
wheels farther apart than the tops.
CARAVAN
Any group of RVs and RVers intentionally
traveling together. They share the same route
and communicate during the trip.
CAMPER
For purposes of this manual, this term refers
to your motorhome.
