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.
Before delivery, had solar panels/controller, 2800 Watt Magnum inverter, and six 6-volt batteries installed. Negotiated G rated instead of the E rated tires.
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.
