Well, you are missing a few numbers to tell how WD is doing, but this much seems to fit.
If the loaded T320SR is 8,600# GVW that fits. Since your F250 gained 1,040# with WD engaged, I’m guestimating your loaded tongue could be in the ~ 1,150 to 1,200# range.
Using the 1,200# tongue estimate that is about 14% loaded tongue. Using the 1,150# estimate that is about 13.4% tongue.
If those tongues weigth pan out, then those are good stable tongue weights in relation to the loaded GVW. It also means you do not have room to add any rear boxes that will reduce that tongue weight.
Now doing more gustimating…. The T320 empty axle weight with WD engaged was 6,420# and now the loaded axle weight with WD engaged is 7,560# is a 1,140 # difference.
Guestimating you gained about 200# TT axle weight from WD, this then lowers the number to 1,140-200 = 940# but then adding in tongue weight gain, guestimating 350# well that adds back to about 1,290# of stuff added to the T320 since you scaled it bringing it home. More or less pending how tools ended up in there….

I can’t really tell a lot more since the weights are not in the right order. The rest are educated guesses.
Next time you go, if you can get these 3 weight sets, then we can calculate LOTs.
1. TV and TT loaded and hitched, WD engaged. Need front and rear TV axles independent values plus both TT axles.
2. TV and TT loaded and hitched, NO WD engaged. Then while right on the scale from step 1. undo the WD bars and let ball hold all the dead weight. Take another 3 scale setup reading. Need front and rear TV axles independent values plus both TT axles.
3. TV only. No TT. Go unhook. Need front and rear TV axles independent values
From those 3 sets of weight all axle by axle we can figure out most everything you ever wanted to know and forgot to ask. We can compare these against the TV axle ratings and TV GVWR and GCWR and hitch WD bars etc.
If you do this at a truck stop, have to go inside and explain what you are up to as they are sort of clueless on weighing TT's. If you tell them after the 1st reading the rest are adjustments and reweighs, the price is cheaper. Pilot is about $1 for reweighs, Flying J's are sometimes free.
If you have access to that grain or recycle scale you where talking about, that will work too and less hassel dealing with a bunch of semis whizzing around you.
