Gross Vehicle Weight Ratings are that. Ratings. Why do the manufacturers place GVWR, GAWR, GCWR tags on their vehicles?
We don't find a trucks GCWR stickered any where on the truck nor is it required to be. A simple gear change/or a tranny change/or different engine will change a trucks GCWR.
GVWR and the GAWRs are a fed requirement and are placarded on the drivers side door.
Feds tell us the a trucks GVWR cannot be greater than the sum of the vehicles mfg axle ratings. In the case of the OP 2500 GM with a 4800 FAWR and a 6200 RAWR could have been 11000 lbs GVWR.
GM has certified the GAWRs which are on the placard and is one big reason trucking laws can use the sum of the GAWRs as the trucks GVWR. A RV person using the same truck may use the same numbers if needed however no where does trucking use the truck makers GVWR to determine a truck payload.
IMO there is no grey area other than on a RV website. Just black and white determined by the truck makers and our trucking weight regulations.
The newer gen trucks with their high GVWRs in many cases will over load the trucks RAWR if payloads are figured from GVWR. Especially the gas powered units.
