The rear view monitoring system may be programmed to automatically engage when the motorhome transmission is placed in Reverse, or the camera may be designed to come on only after turning on the power on/off button. Side view camera lens are often mounted on each side of the motorhome near the fender skirts. To have the side view cameras automatically engage with the corresponding turn signal, press the Camera Auto switch. If you leave the camera button out, the system will run in manual mode and you can choose which side of the motorhome to view by using the Camera Selector Stick.

Use exterior cameras to assist in backing up the motorhome, to check on tow vehicles during drive time, or when passing slower moving vehicles to determine lane changes. Side view cameras perform a valuable function by eliminating blind spots.

Power consumption for most monitor systems is approximately 3 amps. If cameras fail to operate, inspect the fuse and replace if necessary. Fuse locations differ between motorhome models, but should be labeled at the appropriate electrical box.

Disengage the power before cleaning the camera system. Do not use liquid or aerosol cleaners. Clean the camera lens and the monitor by wiping with a soft, dry 100% cotton cloth. Camera systems may include automatic cleaning features such as air fans or washer fluid.

Exterior cameras will not replace the need to physically walk around a campsite prior to backing in. Take the time to visually inspect the area for obstructions that may cause damage to the undercarriage, or holes and soft ground spots that can prevent the levelers from operating as designed. Locate land markings that will help you to back the motorhome into a position that will leave adequate space for retracting slide rooms and awnings.

Never back up the motorhome when a tow vehicle is attached utilizing a tow bar. If someone is going to stand outside and assist you in guiding the motorhome, work out hand signals and verbal instructions ahead of time to avoid confusion. Keep that person visible in the rearview mirror at all times when the motorhome is in motion. If you lose visual contact, stop the motorhome until you once more see your guide in the rearview mirror.

Exterior monitoring systems are offered standard on most models, and are also available after market. In addition to motorhomes, rear view cameras can be installed in the tow vehicle used to pull fifth wheels, travel trailers, boats or trailers. Video cameras are also popular for use inside horse trailers, in combination with an interior dome light controlled from the driver's dash to provide nighttime viewing. Existing camera systems can be upgraded to color monitors and exterior sound. If you are in the market for an exterior camera system, remember that shopping by price may prevent you from getting the best quality of picture or sound.
