I am working with the person who bought my truck to get it shipped to him. He needs to know how much my truck weighs. I'm guessing somewhere around 5,000 pounds, but wanted to know if anyone had a better idea? Its a '79 K20 longbed. 14BFF rear, 10 bolt front, 350, TH400, NP203 with 40" gumbo mudders. Thanks in advance!
