I have a similar question. My 56' Bubble came with a home made battery box attached to the front of the hitch (in front of the gas tanks). What seems odd to me is it appears all of my interior lights are 110 and I don't seem to have any 12v
lighting on the inside. Was that typical in 56'? Does anyone know if originally there was a battery on the unit and if so where it would have been located. Not sure what it would have run since there doesn't appear to be anything in the unit that works off of 12V
. I have a 110 type plug on the front of the trailer that sends power to an old glass type fuse box. I'm told my Bubble originally had an Ice Box (so I guess it didn't need electricity?), a long narrow gas heater, and an stove and oven. No 12v electric water pumps or hot water heater. So does that mean back than 12V wasn't used (except for the exterior trailer lights)?
