I have the SwiftHitch set for about a year. It is a good product but with my truck length (Extended Cab/8’ bed/Canopy) it is barely within its range limit. Any neighbors’ Wi-Fi will interfere. I am very satisfied with the product functionality but limited range is on occasion annoying. I decided to go with the wired option for both the truck and the 21'
Bigfoot trailer. After some search my prime choice is this Rear View Safety set
RVS770616 modified to two rear view cameras instead of one rear view and two side views cameras. This camera has 1/3” instead of ¼” CCD chip so it should have better sensitivity. One camera will go on the rear of the trailer and one on the back of the truck. This particular set was aimed by manufacturer for commercial applications. The LCD Monitor’s built in multiplexer will allow automatic switchover once trailer is hooked-up. They also have
QuickDisconnect accessory which will make truck/trailer interconnect rather robust. This is my next RV project on the list.
