Weighed at CAT scale - Need some clarification

I finally had a chance to weigh our new TT. I made 3 passes. Here are my numbers:

Truck and TT with WD hooked up;

Steer axle: 4080
Drive axle: 4840
Trailer axle: 8240
Gross Weight: 17160

Truck and TT with no WD hooked up:

Steer axle: 3780
Drive axle: 5260
Trailer axle: 8100
Gross Weight: 17140

Truck by itself:

Steer axle: 4260
Drive axle: 3640
Gross Weight: 7900( wife and some gear not in the truck so I am adding 150 lbs to this for a total gross weight of 8050

So, does my trailer weigh 9110(17,160 - 8050)
Is my tongue weight: 1010 (9110 - 8100)

Here are some questions. If my TT does weigh 9110 i have no idea how my stuff weighs a 1000lbs. We were pretty darn light as this was just a weekend trip. No water in tanks(fresh, black or gray).

UVW of TT according to yellow sticker is 7960.
GCWR of camper is 9000
Each axle is 4400 lbs

I assume I am okay on axle weight since my trailer axle weight when hooked up to WDH is 8240.


I am very perplexed at my supposed loaded trailer weight. Tks
