HOLDING TANKS
Storage for fresh water, gray water, and black
water. All types of water are stored and

RV can draw from/hook into, usually at a
campground. Full hookup includes all three
systems available.
HOUSE BATTERY
One or more batteries in a RV for operating
the 12 volts DC lights, appliances, and systems.
House batteries can be 12 volts DC units tied in
parallel or pairs of 6 volt batteries tied in series
(to double the voltage). The term house battery
is of more significance in motorhomes because
they contain one or more other batteries for
the operation of the engine, referred to as the
chassis or starting batteries.

Transforms 12 volts DC battery power into
120 volts AC power. Can be used when
boondocking to power certain devices like
microwaves.

protect the RV from debris thrown up by the
rear wheels.

LEVELING
Using ramps or jacks to ensure a towable RV
is level when parked and/or unhitched at a
campsite.
LEVELING JACK
A jack lowered from the underside of
motorhomes for the purpose of leveling the
vehicle. A leveling jack is designed to bear a
significant portion of the RV's weight.
LOW POINT
The lowest point in the plumbing. Drains are
placed here so that water will drain out of
the lower end of the camper when flushing
or winterizing the water system. These drains
must be closed when you fill the water tank.

appliances such as stoves, ovens, water
