First some questions, What kind of scale did you weigh at? Did each truck axle have it's own scale pad? Did you weigh the rig hooked up on all the readings? Did the trailer axles both sit on one scale pad?

The system I used was the truck stop scales. I weighed hooked up and ready to go on the road. Each truck axle was on a scale pad, the rears in my case both on the same pad. The trailer axles also on one pad. This gave a weight for front axle, loaded rear axles and trailer axles. I then took the trailer and dropped it off in the lot then weighed the truck alone, again with axles on their own pads so that I had a weight on the rear axles unloaded now.

Subtracting the unloaded rear tow vehicle axle weight from the loaded rear axle weight gave me the pin weight.

The only draw back to the truck scales is that it does not give side to side weights or each tire position weights. It is possible to be under the axle loading limit but be overweight on a tire.
