Then drive off scales and go park trailer in parking lot.

Drive truck onto the forward and middle platforms
Push button----'Private' Reweigh

Go park truck, go inside, pay and get your weigh tickets
1st ticket
truck steer, drive axle and trailer axles plus total
2nd ticket
truck steer, drive axle and total

Difference between truck Front and rear axles with trailer and without trailer is trailer pin weight
It's not just rear axle...check for any differences in front axle weights
Depending on hitch placement in truck bed front axle weight could be same, could be less, could be more

My hitch is set 2" forward of rear axle center line and this transfers 150# to front axle when 5vr is hitched plus the weight added to rear axle
So I add the 2 figures to get my pin weight -- 3080# = 22% pin weight on my 5vr

When pull on for 2nd weigh, stop TV same place as first.
Subtract 2nd gross from first, this will give you the weight of the trailer. The first weight slip will give you the weight on trailer axles. Subtract that from the calculated weight of the trailer will tell you how much weight the truck is carrying.
The button is placed for easy reach by the driver of a class 8 truck. For me to reach it I open door, stand up on door sill while leaning on top of door. My weight is still split between same platforms.
