I was looking at a Dodge ram 3500 4x4 with dual rears, and was wondering if you can take the pickup body off and throw a dump body on it and if so is it to expensive to even consider or reasonable. I already have a dump truck but its only a 4x2 and was hoping to get a 4x4 for the winter. I know I can just go buy a 4x4 dump truck but the dodge is very clean, and within my budget.
