Re: House battery location on a 2004 u320.

Mine are not very conveniently located. I have a 40' 2004 U320. If yours is like mine, I suggest you open the lower storage bay, pull the storage tray/joey bed all the way out, then go to other side and look in. You should see an access panel on the vertical wall that you will have to remove in order to get to the batteries
