A dump bed insert like that one sells for 1500+ bucks around here,maybe 2K now,I priced one years ago,and found putting a "real" used dump bed on the truck was cheaper!...
I'm not too much of a Ford fan--but if I saw a 1980's-90's F-150 or F-250 4x4 with the 300 six and a 5 speed,I'd be highly tempted to own it,especially if it was cheap...few exist here any more--the few left that aren't rotted or junk for sale go for top dollar,and the rest of the owners who have one dont want to part with it..Fords seem to not rust away as bad as GM's around here..
