Went to cat scale today. Following this from a post I found with how to use the weights.. And from another post I had in towing.

Weighing #1 -- TT attached and Weight Distribution Activated
Let Front Axle Load be "FA1"
Let Rear Axle Load be "RA1"
Let TT Axles Load be "TT1"
Then, while in same position on scales, take
Weighing #2 -- TT attached and Weight Distribution Not Activated (WD bars unloaded, but hanging in place)
Let Front Axle Load be "FA2"
Let Rear Axle Load be "RA2"
Let TT Axles Load be "TT2"
Then, drive off scales and drop TT. Return to scales and take
Weighing #3 -- TV only -- TT Not Attached
Let Front Axle Load be "FA3"
Let Rear Axle Load be "RA3"
From the above values, you can calculate:
TV weight = FA3 + RA3 4480
Gross Combined Weight = (FA1 + RA1 + TT1) 8820
{should also be equal to (FA2 + RA2 + TT2) if scale weights are correct}
TT Weight = Gross Combined Weight - TV Weight 4400
Tongue Weight = (FA2 + RA2) - (FA3 + RA3) 420 or [COLOR=]340 with WD
Load Transferred to TT Axles
when WD System is Activated = TT1 - TT2 80
My axle weight ratings on truck are 2700 lbs
My truck GVWR is 4900 lbs
This was empty just me in truck. Propane filled. Seems I have 500 lbs to work with on the truck side roughly.
These #'s look right?
You see no #'s are over my axle ratings. Also none of the combined axle ratings go over my GVWR
Here are my 3.
1 WD activated
2 WD unhooked
3 truck only
WD activated

WD disconnected.
