AC ELECTRICITY Alternating current also known as shoreline power. For purposes of this manual, it refers to 120-volt 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 An anode rod, when used in a water heater, attracts corrosion causing products in the water. These products attack the anode rod instead of the metal tank itself. The anode rod should be inspected yearly and changed when it is reduced to about 1/4 of its original size. The rods are used in steel water heater tanks - an aluminum tank has an inner layer of anode metal to accomplish the same thing. Anode rods should not be installed in aluminum tanks!
AUXILIARY BATTERY For purposes of this manual, the term refers to the 12-volt DC group 27 deep cycle battery (customer purchased) that should be installed in your RV.
AWNING A roof-like structure made of canvas or other artificial 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.
BLACK WATER Term associated with the sewage holding tank. The toilet drains directly into this tank.
BLUE BOY Also known as a honey pot. Refers to a portable waste holding tank that has wheels on one end. These tanks often are manufactured out of blue plastic, hence the nickname.
BOON DOCKING Also known as dry camping. Camping without electrical and water hookups.
BREAKAWAY SWITCH An electrical switch on trailers designed to engage the breaks in case the trailer breaks away from the tow vehicle. The switch is connected by a cable to the tow vehicle. Breakaway is detected when the switch cable is pulled out during vehicle separation.
BRAKE CONTROLLER A device (customer supplied) mounted under the dash of a towing vehicle to control the braking system of the RV. Most brake actuators are based on a time delay application; the longer the brakes are applied tighter the trailer brakes react
BRITISH THERMAL UNIT (BTU) Measurement of heat that is the quantity required to raise the temperature of one pound of water 1°F. RV air-conditioners and furnaces are BTU-rated.
CAMBER (WHEEL ALIGNMENT) The number of degrees each wheel is off of vertical. Looking from the front, tops of wheels farther apart than bottoms means "positive camber". As the load pushes the front end down, or the springs get weak, camber would go from positive to none to negative (bottoms of wheels farther apart than tops).
CAMPER For purposes of this manual, this term refers to your fifth wheel RV.
CAMPING An outdoor recreational activity involving the spending of one or more nights in a tent, primitive structure or RV at a campsite with the purpose of getting away from civilization and enjoying nature.
CAMPSITE The term usually means an area where an individual or family might go camping.
CARBON MONOXIDE A colorless, odorless and poisonous gas.
CARGO WEIGHT The actual weight of all items added to the Curb Weight of the vehicle or trailer. This includes personal cargo, optional equipment, and tongue or king pin weight.
CARGO CARRYING CAPACITY (CCC) Equal to GVWR minus each of the following: UVW. full fresh (potable) water weight (including water heater), full propane weight and SCWR.
CITY WATER Term associated with the water supply you hook up to at the campsite. It is called city water because water is pulled from a central outside source (like a city) and not the fresh water tank.
CONDENSATION A result of warm moisture laden air contacting the cold window glass. Keeping a roof vent open helps to reduce the humidity levels. Added roof vent covers help to prevent cold air from dropping down through the vent while still allowing moist air to escape. Using the roof vent fan when showering or the stove vent fan when cooking also helps prevent excess moisture buildup.
CONVERTER A device that converts 120 volt A/C (alternating current) to 12 volt DC (direct current). The RV devices mostly run on 12 volt DC power that is supplied by the battery, which allows the RV to function independently. When "shore power" (an electrical supply) is available, the converter changes the voltage from 120 to 12 volt to supply the appliances and to recharge the battery.
CURB WEIGHT The actual weight of a vehicle or trailer, including all standard equipment, full fuel tanks, full fresh water tanks, full propane bottles, and all other equipment fluids, but before taking on any persons or personal cargo.
CURBSIDE This refers to the side of the camper that faces the curb when parked. Also referred to as the door side or DS.
DC ELECTRICITY Direct current also known as auxiliary battery power. For purposes of this owner's manual, it refers to 12-volt DC (abbreviated 12 VDC).
DEALER For purposes of this manual, this refers to the independent dealer authorized to sell and/or service your camper by Grand Design RV. This term will be used in this context unless specified otherwise.
DINETTE Booth-like dining area. Table usually drops to convert unit into a bed at night.
DRAIN TRAP This is the curve that is in all drains. Water is trapped in the curve and creates a barrier so tank odors cannot escape through the drain.
DRY CAMPING Camping when there is no city water hookup or shore power (i.e., using only the water and power available in the camper and not from any other source).
DRY WEIGHT The actual weight of a vehicle or trailer containing standard equipment without fuel, fluids, cargo, passengers, or optional equipment.
DSI (Direct Spark Ignition) This term refers to the method of igniting the main burner on a propane fired appliance. The burner is lit with an electric spark and the flame is monitored by an electronic circuit board. This ignition system is used in refrigerators, furnaces and water heaters. There is now a version of stove tops that light the burners with a DSI ignition.
DUAL ELECTRICAL SYSTEM RV equipped with lights, appliances which operate on 12-volt battery power when self-contained, and with a converter, on 110 AC current when in campgrounds or with an onboard generator
DUALLY A truck having two wheels on each side of the rear axle for a total of four wheels
DUCTED A/C Air conditioning supplied through a ducting system in the ceiling. This supplies cooling air at various vents located throughout the RV.
DUCTED HEAT Warm air from the furnace supplied to various locations in the RV through a ducting system located in the floor. (similar to house heating systems).
DUMP STATION Site where you drain your gray water (waste) and your black water (sewage) tanks. In most states, it is illegal to drain your tanks anywhere except dump stations.
DUMP VALVE Another name for the T-handle valve used to release and drain the black tank (sewage) and gray tank (waste).
