Picked up our new Voltage 3200 last Monday. Only issue so far is the converter smoked soon as I got it home. Now I have to take it back in after all the snow melts. The dealer has been very helpful and pleasant to deal with so far.
I'd like to see your battery mounting configuration.
I can tell you that the entire floor space in the generator compartment is taken up by batteries, but they fit in there perfectly. There are three battery boxes sitting side-by-side. I'll try to get a photo this weekend.
