You can buy cameras, cable, and monitors individually on eBay and Amazon and put together the system you want if you're interested in a small project. I got a bullet camera from "eSky" as well as a small LCD monitor and a rocker switch. Put a small hole in the front of the driver foot well, install a grommet, and run the wires through there under the coach. A little dab of silicone sealant when the installation is complete and tested will weatherproof it nicely. They've got different sizes of monitors and they're interchangeable. I went with a camera that just has a little metal pedestal that its mounted on instead of the license plate mount so that I could make sure it was right in the middle and that the ball for the trailer hitch was visible. I had a conversion van that I put a camera in once and I used the license plate attached camera which meant that the camera was off center and the bottom of the plate cutout obscured the view of the hitch ball making the whole setup almost useless. I still need to tidy up the wires on the back of the coach - I ran them up through the corner trim and over to the center behind another trim panel, but it could use a little work - it's just not "neat" enough for my liking. My thought was to keep the wires exposed, though, to avoid putting another hole in the rig that would need to be sealed and resealed and continually maintained to avoid water damage.
