TRAILER MOUNTED BACK UP CAMERA

there was a post on this not to long ago. I helped two guys out that PMd me, sent them a vid of what I have and wording on how I hooked mine up...I did not want to go wireless, wired seemed the only way to go for me....I love my camera that is 35' away from my back bumper.....makes backing up easier and the wife and I can start camping still liking each other. Radios are still a must, but cameras are awesome. Would not go with out one. I really like it going down the road, I can see if some one is riding my a$$, and when Im going into another lane, there is no guessing if there is room, with a camera, you can see.

ohh, and I have 2 cameras and a 7 inch screen, you can switch between the two. under 200 bucks
