RV Terms and Definitions 05

Back-up monitoring system – camera and navigation screen used as a aid to backing up or reversing the RV.  The camera is mounted on the back of the motorhome and the screen on or near the vehicle’s dashboard.  Since the camera faces rearward, the display on the screen is horizontally reversed so that objects on the vehicle’s rear right show up on the right side of the screen and those on the rear left show up on the left – in other words, the camera output is displayed in a mirror image format oriented as a driver would see in a rearview mirror. The system can also be used in the same manner as a rearview mirror to monitor traffic behind the RV as well as anything whatever is being towed, though this may be limited due to the mounting angle of the camera and the use of a wide angle lens.6

Note: This post is part of a continuing series created during the development of a glossary of RV Terms and Definitions for a new website.

Ball mount – the part of a ball hitch that the trailer hitch ball is attached to.  Receiver-type hitches use removable ball mounts while fixed drawbar hitches – attached to the vehicle frame – and bumper hitches have integrated holes for attaching the trailer hitch ball.

For safe and comfortable towing, the trailer should always be as level as possible. A level trailer will put less strain on the connection between the trailer and hitch. It will also help the trailer stay in line behind the vehicle. Because trailer and vehicle heights often differ, a ball mount with a Rise or a Drop may be needed.7

Basement, basement model – storage area below the floor of the recreational vehicle. Basement storage is more commonly found on Class A motorhomes, some Class C motorhomes, and the forward storage area of many fifth wheel trailers. Basement storage areas allow pass-through storage, where one or more compartments can be accessed from either side of the camper.  Basement models are RVs that incorporate large storage areas below a raised chassis.

Battery – direct current (DC) electrical power source.  RVing batteries have two applications that require different battery designs: (a) powering house or coach DC components and (b) starting power for the engine and powering chassis DC component for a motorhome or tow vehicle.

Batwing antenna – roof mounted television antenna that can be raised and lowered from the inside of the RV using a hand crank combined with a manual control used to rotate the antenna. Batwing antenna are characterized by two horizontal “wings.”
