What would be perfect would be a Group 41 deep cycle.  Dream on.

I believe Karl Mullendore figured out that the max amp-hours you could
fit under the driver seat was to put 4 UB12220 batteries there.  I can't
find anything on his site now--he's moved on to bigger things under
other places.  (westyventures.com)

Here's a pix of the setup--4x22 amp/hour batteries:

Hmmm....  I wonder what he has under his driver seat now?
