Pickup truck: from OEM info GCWR is 23,000lbs. From door sticker: Front axle 5200 lbs, rear axle 6200 lbs (total 11,400 lbs), but the sticker GVWR is 9900 lbs.
Neighbor's Kenworth: from OEM info GCWR is 140,000lbs. From door sticker: Front axle 13,200 lbs. , rear axle 46,000 lbs (total is 59,200 lbs.) Sticker GVWR is 59,200 lbs. (it appears someone at Kenworth can add?)
Couple of items to ponder:
1- By "bridge law" the tractor can only weight 47,200# on the interstate That's 34,000# tandem axle and 13,200# for the steer (single axle is 20,000# or axle/tire rating). He can only do the 59,200# off road. 46,000# (2 - 23,000# axles) rears last longer and durability is the name of the game. When you rack up 500,000 miles in 4-5 years (half that time for a team) you want the truck to last. As for the 140,000# GCWR, the standard truck is limited to 80,000# unless you have special permits. This truck will normally operate no where near it's design limits.
2- There are other limiting items in the drive train other than the raw axle ratings of a pickup. Brake size, transmission, u-joints, engine, suspension, all affect GVWR.
