Your 1999 Roadtrek 190 Popular House Battery Location

I just check our battery location in our 1996 190P. It is, as has been said, in the floor, under the carpet, at the rear drivers side. It is a deep cycle group 24 nestled in an aluminum box.
I was a bit disappointed in that it is only a group 24 (small size). But i guess that was standard for the time. I have a newish group 27, in a battery box that i was thinking i could mount & anchor above the existing one, under the bed. I would need to get a vent kit & vent it outside.
