Husker, I presume your ladder is mounted off to one of the sides of your camper... with 2 simple holes and 2 grommets why not utilize the exterior "conduit" on the back of your camper.. your ladder ?? The majority of the RV ladders are constructed of hollow aluminum so drill a hole on top of the rail ( I think I'd put the first hole on the side of the tube) then run your wire down through the tube of the ladder rail and drill an exit hole on the bottom with a grommet. Now you can run your wires up to the front of the unit utilizing the frame rails. I'd fish some nylon string through ladder so you can pull it through without any issues. I dont have a ladder on mine but toying with the idea of installing a high mount camera as well.
