So how important is the trucks GVWR number for figuring how much hitch weight a particular truck can safely carry.
Points to ponder for the OP about a GVWR number.
One TBN member says his 6.0 2500 chevy has a 3640 lb payload sticker and had basically the same question as the OP.
His math shows the truck with a 2980 lb rear axle scaled weight. Now add 3640 lb in the bed = 6620 lbs on a 6200 RAWR for a overload on his 17" wheels and tires.
Gas or diesel same configured trucks weigh about the same on the rear axle from the factory.
I'll use Ford's 350 SRW for another point about GVWR.
Ford markets a F350 SRW with 10000 GVWR and 11200 GVWR in the same exact truck.
The trucks carry the same FAWR/RAWR same engines/trannys/frames same brakes/spring packs tires and wheels.
But Ford gives them a different number on the yellow payload sticker.
One F350 SRW 10000 GVWR owner on another rv website was convinced by the forums weight police he had to upgrade to the same exact crew cab 172" wheelbase/6.7 diesel 4x4 with a 11200 GVWR to pull a 12k GVWR 5th wheel trailer.
He never came back with his solution but hopefully he was smarter than they were.
"..Ford Markets ..." Substitute Dodge, or Chevy, the key word here is "Markets"! As I have expressed in other posts, Dodge 2500, is basically a SRW 3500, difference is wheels, tires, and springs. The big 3 would rather you spend your money on buying a different truck, then trying to adhere to that "yellow sticker" which is confusing and if you look closely contradictory! Your big issues to cover first would be wheels and tire ratings, if you routinly exceed those you will have problems. Next would be springs/air bags, big thing here is the ability to tow level. Gas or diesel, both can "tow" within reason.
