I was just on the Ford Commercail site. Does anyone know what wheel base would need to be ordered for at least a 12 ft. dump be put on a F-450 Crew Cab 4x4? I priced the 200 in. was around 36,000. What ft. dump could be put on the 200in. truck, and about how much would the dump bed cost me? Just wondering if I could get it all for about 40,000-42,000? Thanks for the replies. BTW I did not know if the 200in, was for the whole truck or just the bed area, not including engine space?
