Bought a 99' superduty, 4x2, 5.4 auto, xlt, supercab, 8'box. ANYWAY.....I pulled the box off and put a servicebody on it (sharp looking truck). I didn't get a chance to weigh it before I did this and am wondering how much extra weight I am hauling around now. I can take it to be weighed now, but how can I find out exactly what it weighed before?

 

Try NADA Guides. Once you configure it to get a value it gives you a weight as well.
