Its an 82 1 ton reg cab. dually. 4x4 w/ 350?

I wouldn't want to carry it very far, should be the neighborhood of 6000-6500lbs

I would also put it at 6000-6500 pounds. My 1/2 ton frame, short bed with 1 ton running gear is 5500 pounds. The extra frame and length should add at least 500 to 1000 pounds.
