Great idea for the hitch. Always a problem hooking up the Trailmanor when alone.
I need to visit PEP Boys Automotive and see if the $100.00 wireless camera signal will reach my truck cab from the rear of the Trailmanor. The distance will be about 35 feet
. Then there is all that metal between the TV cab and the rear of the TM.
I'm not sure but I think that the wireless cameras operate on a battery. If not, the rear tail lights are a good option.
