Tongue Weight Part 2 CAT Scales
Hello and thanks all in advance! So I went to the CAT scales prior to my long Yosemite drive and gained some numbers. I was able to gain a 3 different weights, trailer alone, truck alone, and th...

If I'm understanding your numbers properly, you have about a 180-200 pound discrepancy between your separate weights and your combined weight (with the combined being the lower weight). Possibly you ended up weighing yourself twice in the separate weighings. You also have three ways of figuring the tongue weight; however, since the numbers from the various weighings don't all add up the same, there are some significant variations in the results.
For the trailer alone numbers, I can only assume the "steer axle" weight is the tongue weight (on the tongue jack), and the "drive axle" weight is the weight on the trailer wheels. That would put the tongue weight at about 15%, which seems reasonable. This has the advantage of directly measuring the tongue weight without computation.
Subtracting the trailer axle weight in the combined weighing from the known total trailer weight in the second weighing gives a tongue weight of 640 pounds, or about 12%.
Computing from the truck weight (2920 + 3740 - 6190) gives a tongue weight of 470 pounds, or about 9%. This differs from the 12% because of the 200 pound discrepancy in total weight between the first two weighings and the third one. These differ from the trailer alone because of this discrepancy and perhaps also because of a weight distributing hitch (if you're use one).
