The draw of a 36 cell system would be significantly lower than the draw of a 16/18 cell system. I don't think you would have any trouble at all with the gp2000 or gp2200 cells' ability to cope with the draw. The 2200s can handle similar load as the 3300s, so these won't have any trouble at all. Enough of the 2000s will reduce the amp draw enough to power the truck without breaking a sweat as well!
