Yes, the switch for the coach batteries should be where stardalo said. There is not a cut off switch for the chassis batteries. I installed one, on my 2002 Journey, back next to the battery trays to solve the problem of the small drain on the chassis batteries when in storage. John

Like Stardalo said, second or thrid switch down on the right on dash, AUX Battery cutoff switch, cuts off all power to the coach. When you turn it off you should hear a CHIRP sound.
