I also installed this same system in ours 2 years ago and I think it's great for the money. I ran the new cable (provided) as the ends were different than the cable pre-installed in our winnebago. I installed the monitor above the useless rear view mirror in the coach and have it wired to be on full time with the key to monitor the toad. Works great so far. It also has two additional camera ports, I am contiplating adding two side cameras to the rear view mirror arms that would switch the monitor view when that side turn signal comes on, they provide trigger wires to do this also.
