Moderators, if this the incorrect forum to post this, please help me find the correct one. Thanks!

Hi all! In preparing for a multi-month cross-country trip beginning in May, we wanted to make good use of our current camera system in lieu of the Furrion prep supplied by GD on our new Momentum. I'm currently using a 4K dash cam system with a rearview mirror-like screen with additional input from a rear camera mounted on the rear bumper of my truck.

On our previous bumper pull TT, I was able to extend the wiring under the unit and up the back wall to the camera prep location where I mounted the small 1080p camera to act as the rearview in the cab of the truck. That was for a short trip and had duct tape holding the wiring to the back exterior wall of the TT, not ideal for this upcoming trip in the new unit.

With knowing the history of this application, I would like to accomplish this on the new unit with one of the following scenarios:

1. Run extension wire from hitch wiring point, through the ceiling the length of the unit to the prep location on the rear exterior wall (preferred method)....OR
2. Run extension wire from hitch wiring point, underneath the length of the unit, and into the side wall to traverse up to the prep location... OR
3. Source a wireless transmitter/receiver set that works with the system to avoid running extension wiring.

I'm laying out all of this ground work to get feedback or alternative measures to attain similar results and to ask if there is a common wiring races/space in the ceiling/basement/walls of the unit to accomplish the above scenarios or if the prep location has more than 12v power run to it.

Any insight into this is much appreciated!
