House batteries are 6volt while chassis is 12 volt, don't try to swap them. I carry a small battery charger with us when we travel, recommend you get one also, really helps when I leave the key on in the toad. Also, don't you have coachnet since you have a new unit? Would call them and let them help you. Also on the aux start, you need to hold it down for it to work.
