Gross vehicle weights and tires
OK, been on the road for several weeks now and stopped in at a flying j to fuel. Hopped on the cat scale while we were there and found we're about 600 lbs overweight on the rear axle but still below G...

The axles will support 8900 lbs. or more. The 4 tires at the rear should be able to support 11,000 lbs. or more. Subtracting the weight of the truck with no load will give you an approximate payload capacity. The GVW is a number that indicates a class of truck for the feds, marketing, and the DMV. It is not a calculated value for your truck the way the "payload capacity" or GVWR numbers.
Even these numbers are calculated by the factory and based on the weakest link as the truck is configured when it leaves the factory. Nothing to keep you from upgrading the rear springs, shocks, rims, tires, adding a anti-sway bar, etc. to increase the safe payload for your truck.
The GVWR is also used to classify trucks and the big three all want to claim they sell more trucks then their competitors. It is why Ford even goes so far as to produce a pickup version of their F-450 and lumps its sales numbers in with those for the F-250 and F-350 pickup trucks.
