The chassis cabs can be outfitted with a bed, utility body or flat bed. I plan on adding a flatbed with utility boxes above and bellow. The lower boxes will eventually get built out as battery boxes which will power an inverter for the TC. Initially the charging will come from the truck or an on board plug in charger, but solar will play a larger role as funds build. I see this battery setup adding 1000 lbs to the truck.
The Class 4's have greater towing capacity than the Class 3's and make good toters for heavy FW and GN trailers, but do little to add payload since they are typically built on a heavier chassis and that weight takes away from the capacity.
