the unit that i purchased from ebay has 100 meter range (300 feet) so the picture is great. from the monitor in the cab of my truck to the camera on the back of the TT is about 40 feet. the monitor is mounted high in the cab right in front of the rear view mirror and the camera is mounted on top of the TT in the center about 8 inches above the running lights. the power for the camera comes from drilling a hole in the roof/back siding and running the wire to the curtsy light in the bunk house, and that was the hardest part.....
again sorry for no pics i store my TT at my brother-in-laws and don't get over there that often. but i will update this thread soon with some.
