Just to clarify, hook the one side on the Excursion to both to the battery terminals, and just positive battery post on camper and Negative to clean frame?
I just got off phone with Jayco Engineer and he wants me to take down my under carriage and cut the wires on the motor to bypass wiring and connect a battery to the wires to get the slide in. He is suggesting the dealership run a new wire to the slide motor, but the only covers the 1 slide....
