one other thing you need to determine. How accurate is the scale you weighed the truck on?
The CAT scales (local truck stop) where I weight my rig guarantees their weights for the truckers. However, I don't think they guarantee it to the pound, but I don't have a scale weight printout in front of me to know for sure.
I remember reading years back that CAT scales have a 200k capacity with 10,000 divisions. So the best you'll be able to get is ±20 lbs. They are compliant with NIST standards and are normally certified by the state annually, so the number should be fairly accurate.
