Has anyone added rearview cameras to their truck and trailer? After backing a 40' + fiver into tight places for the past 9 years, I finally ordered a four-camera system to install this winter in Key West. It has two surface mount cameras, one each for high on the back of the truck and trailer, and two side mount cameras for the fiver. It includes a 10" display. Cameras have night vision and sound. It will be a lengthy job, especially derermining where each camera should be mounted and where to run all the cables. I ordered the trailer/truck interconnect cable for an extra $100 to keep thing clean and reliable. I'll try to post photos in the spring when its done. Your comments and questions are appreciated.
