I've been toying with the idea of a backup camera both for my TV but also for the rear of our 22 ft toy hauler. What I have in mind would be a single 7 inch monitor that I could switch between the two cameras but not see both at the same time. I hear that the wireless models don't seem to perform well but are way easier to install/read cheaper. I figure that there must be people on this forum that have one or the other so what's your opinion and if you don't mind saying what brand, how are they working and how much they cost that would be great, thanks Gerry

What 2 cameras would you use? Like where would they be on the RV. I might be able to help. Ive ran CCTV systems before and Im also in the TV field with my job.

I haven't decided on anything yet except the fact I want two cameras and a 7 inch moniter that I can switch between cameras. As for the location on the RV if practicable above the ramp center seems best.

Yea Best would be wireless not only for ease of install but most low end camera use cables that they only make. I would try to get a camera that runs on the 5GHZ band its the less used and no real interface on the road.
