I asked a T.T. dealer how you keep the camper battery charged when your traveling. He said that it automaticly charges from the toll vehicle when your driving. It seems to me that all the wires to the trailer are only hot when you apply the brakes, lights signals, etc. So how would that keep it charged. I am wiring my own toll vehicle and I want to make sure everything is wired right. I went back to the dealer and asked him that question. He said he didn,t know. Not to smart a dealer I think. Can any body help me with this. Thanks for any info. Lou :question:
