Kelly, it does seem kind of high for times youve run and what you've removed/added to the truck. Id go to another scale and get a 2nd opinion.
Any chance scale was wrong?
It is a scale used for trade. they are only allowed to be out 100lbs. on 80,000lbs. but you never know. I'll weigh it at a different scale.
Either way thats a damn fast truck not matter what it weighs.
