I have a old body style 88 dually. It currently has a flat bed on it and it is ugly as sin. I want to put a regular dually bed on it. I think it is the R/V chassis. Will a regular bed fit in it, I had a 1992 dually and for some reason the rear end looked wider then the one in my truck now. I just don't want to purchase a bed and have it not fit or look rediclous. (p.s. i spell so bad that spell check doesn't know what the hell im saying.
