Re: Heaviest GVW on a square body?

The highest GVW I've seen is 10500 for 2WD, 11000 for 4WD. C30/R3500 or K30/V3500 with dual rear wheels and C7C (2WD) or C7E (4WD), heavy duty chassis option.

The payload capacities are very close because the 2WD truck itself it lighter with the 2WD front end vs front axle and no transfer case.

Also, the shorter wheelbase Cab and Chassis has the highest payload because the suspensions are the same between the 135.5" cab and chassis, 159.5" long cab and chassis, and the 164.5" crew cab frames but the short one (not short bed, shorter of the cab and chassis trucks) weighs the least.
