Since pretty much the day we bought it, we’ve felt that our RoadTrek 210 Popular RV would benefit greatly from a backup camera. Well, the driver would benefit more I guess, but you know what I mean.
After we bought the pickup truck, I had done some research and found out that it was fairly easy to retrofit an OEM-type of backup camera to it. The truck was already pre-wired up to the mirror, so eBay turned up an OEM backup mirror with built-in monitor, and the necessary adaptor to plug in any camera. The local stereo shop sourced an OEM-style camera that hides in the tailgate handle trim. They installed the whole thing, and it’s worked great since.
