CAT Scale Weights

The OP did say in travel trim...which is the correct way to conduct this test.

A family of 4 can easily push 600lb. 300lb firewood. 120lb generator. 150lb bikes. 100lb running boards, 200lb fiberglass cap....that's pretty close to 1500lb in the truck before hitching up (the exact makeup might vary but not unheard of numbers).

The only questionable part is going from #1 to #2, the truck axles go from 7500 to 7920 which implies a 420lb hitch weight on a total trailer weight of 5040lb or about 8% hitch weight. Not unbelievable but marginal for good towing.

I would look at shifting more weight to the front in the trailer to get that percentage up.

I agree, their is an error in the truck alone numbers. Assuming the axle weights are correct, the truck is 7,500#

If there is no typos on the 2nd and 3rd set of numbers, then the TT tongue weight is too light at 420#. The water weight in the fresh tank, if is a true 2/3rds full is 33 gal, or 268# of weight behind the axles. That water weight will reduce the loaded TW. If we had some distances, ball to center of rear axle, center of rear axle to center of the tank, I can tell how much TW reduction the 268# is.

Bottom line: Your loaded tongue weight is too light. Ideally you get up into the 12 to 13% TW / loaded GVW of TT range to give you some freedom to move a few things occasionally or an LP tank go empty.

The truck loading is not far out, the TT TW should be adjusted, and that will affect the truck loading to go over again.

Good for you taking the rig to the scales and providing all the ratings to help us look at what you came up with.

Hope this helps
