Thoughts on my scale numbers?
Finally got around to finding and using a CAT scale on our way to a campground. Packed as normal for a four day weekend. Wife myself, two bikes and a small tote of firewood. Camper is a Flagsta...

Jack,
Here's the problem with the numbers:
The indicated tongue weight using TV only data and TV+TT with no WD is (3080+3700)-(3500+2740) = 540#.
Since the brochure hitch weight is 597#, it's quite unlikely that the loaded TW can be 540#
The initial loss of 420# on the steer axle is consistent with a tongue weight of about 1020#.
The initial gain of 960# on the drive axle is consistent with a tongue weight of about 680#.
Changing the "TV only" steer axle load to 3360# gives:
The indicated loaded TW is (3080+3700)-(3360+2740) = 680#.
This value is more consistent with a brochure TW of 597#.
The adjusted initial loss of 3360-3080 = 280# is consistent with a TW of 680#
A TW of 680# plus the TT axle load of 5080# gives a TT weight of 5760#.
The corresponding TW% is 680/5760 = 11.8%.
For comparison the dry TW divided by the shipping weight is 12.0%.
The adjusted net load reduction on the steer axle would be 3360-3280 = 80#.
Where were you positioned when the three sets of loads were measured?
If you were in/on the truck for some of the weighings and somewhere else for others, that could explain the discrepancy.
