My stickers and the tow guide don't seem to agree.
White sticker on door says:
GVWR: 10,000
GAWR front: 5500 at 60psi
GAWR rear: 6500 at 80psi
Yellow sticker on door jamb:
Combined weight of blah blah blah: 3,104
Inflate tires to 60 front and 80 rear.
I assume this means my empty truck weighs 10,000 - 3,104 = 6896. That doesn't match anything else I've found.
Guide says 6,703 with payload of 3,300.
GAWR rear 6000.
GCWR 19,800
Guide says Mega Cab (mine ain't)
GAWR rear 6500
GCVWR 19,800
No guide entry for crew cab with 6500 pound rear axle. Both CC with 6000 pound axle and MC with 6500 pound axle use 19,800 for GCVWR. I suppose that's my number and it's based on the 3.73 gear as much as anything.
I'll scale it soon with a full tank of gas, hitch installed, and sway/distribution bars in bed of truck near tailgate. Now, replace 3,104 with 10,000 minus actual weight of truck with "truck stuff." This new number minus me, her, and a cooler, gives me available tongue weight capacity.
I assume then that I verify all axles (including trailer) are good, truck "all aboard" plus tongue is less than 10k, and the best guess GCVWR is 19,800 for lack of a better number.
