True Truck Payload

Per my knowledge all states and provinces allow registering trucks at higher GVWR and since vehicle weight doesn't change, that come to higher payload.

My state is one that doesn't use any type of weight numbers to register our non commercial trucks.
Just the vehicles axle/tire load ratings are used in determining a over load condition not any type of weight number.

Fords F350 srw is a classic example how silly the yellow payload stickers are. F350 srw has 13 different gvwr ranging from 10000 lb up to 11500 lbs. We can get a F350 srw in the same configuration with a 11500 gvwr or a 10000 gvwr. Both are identical from the ground on up.... the only difference is the gvwr number and the payload sticker.

More input on the subject.....This paste and copy from a automotive engineer ;

***I'm a retired auto engineer and Marketing has a big impact on GVWR. As a engineer, it was our job to make sure the frame, brakes and powertrain components were designed well above the GVWR ratings that Marketing wanted, so we would design in a safety factor for each component. You don't really think we would build a truck and then test it to determine what the surprise GVWR number should be!
Axle ratings are also well above the GVWR rating and in commercial vehicles, axle ratings are the pay load determining factor and even they have a big safety factor designed into them.
It would be unusual for a lawyer to accept a overweight case unless it was grossly over the safety factor weight and even then a vehicle manufacture would not share that info because it is not a hard fast number that will break if one more pound is added.
There are many videos of million pound plus loads being moved by trucks across country. It's all about the axles.***
