Calculating TT options for our truck
I was hoping to get a little input or "shove" if we are off track. We are trying to find what size tt our truck can tow. I can't get the truck to a weigh station till this weekend, so we are using Goo...

Once the rear axle weight is determined at the scale then subtract this from the rear axle weight on the door tag. This will give them a baseline on how much payload they have left for tongue weight..( Or any other items or persons.)
If we assume an additional 420# for weight of OP plus husband plus "buffer", the truck's unhitched GVW would be 6600#.
Based on the truck's front and rear curb weights, it is reasonable to assume the 6600# would be distributed approximately 3800# on the front axle and 2800# on the rear.
Since the rear GAWR is 4050#, your method of calculating payload as the difference between rear GAWR and measured rear axle load would give a calculated available payload of 4050-2800 = 1250#.
If we then add the calculated available payload of 1250# to the assumed GVW of 6600#, the TV's resulting GVW would be 6600+1250 = 7850#.
The resulting GVW would exceed the TV's GVWR by 7850-7200 = 650#.
Is this what you had in mind when you said, "You can go over your gvwr if needed.."?
Payload is based on axle weights.You did get this part correct because you said "axle weights" rather than "rear axle weight".
Available payload is equal to the GVWR minus the sum of the front axle weight and the rear axle weight.
