Really Hard to say, My old steal body did not have floors. I can say this, the original body is like a beer can when compaired to this N.A.M. body. If I had to put a weight on the N.A.M. body I would say 335 to 350 pounds. This is just a guess! I can say that I used to put the original 32 body on the chassis by my self but there is no way in hell I could do it with this new body. Hope this answers your questions. OH, by the way I do not miss the old body at all, I just wish I would have bought this N.A.M. body a lot sooner than what I did.
