I found this in the on line generic manual for a 2018 Palomino FW under Safety Devices
The backup camera (optional) is located in an elevated location on the rear wall, directly below the center running lights. It is a color camera with a built-in microphone. The connection cable exits the camper in the roadside front corner next to the truck electrical connection. The mating harness and monitor are available from your Palomino Dealer.

I suspect the "camera ready" means the wiring exists, as described. Call the dealer or manufacturer for details??
