I believe the 32' restriction applies to the invisible trailer option for a bumper tow trailer, when you set the camera for a fifth wheel trailer that option isn't available. My 5th wheel is 45' and the cable for the camera is the exact length that I needed once I moved the camera port into the bed of the truck, I also ran my camera cable under the 5th wheel and fished it up by the generator and pulled it out next to the pin box.
