Your trip to the Cat. Make 1 pass, hooked up like you tow, another with just TV. I have never understood what useful info is gained with loose bars, but the change in weight of TV, and where that weight rides is important info.
BTW, if you tell them it is re-weigh for the 2nd (or more) passes only charge a fraction.

For an extra $2-3 get all the info.

It's technically possible to back calculate with just the 2 measures but beyond most people's understanding of how to calculate.

I don't see how that's possible because you'd have to guess at a variable. For example calculating tongue weight would be impossible from one pass with just the truck and the second pass with weight bars connected which will put weight on the front axle and ADD weight to the trailer axle. You'd have to guess what the tongue weight is.

Well first you must understand the TW when the trailer is setting on the jack is meaningless. The number you need is the TW when hooked up, ready to go down the road.* Once you get that idea between your ears you have 3rd grade arithmetic following a 5th grade word problems. Now this is approaching the extent of my education level, other than what I learned making a living, but I will try to break it down.
The 2 passes will give you 7 numbers. TV steering (S1), TV drive (D1), TV gross (G1), Combination steering (S2), Combination drive (D2) trailer axles (TA) and Combination gross. (G2)
Want to know the TW while in operation? Add (S2) to (D2) then subtract (G1). Trailer weight? Subtract (G1) from (G2) How much of TW is transferred to steering? Compare (S1) to (S2)

*And before you go talking accuracy, understand if you need a WDH, the TW that shows when bars are loose will be more than actual.
