steel beds for 72. as for the 51,000 it's probably more like 151,000. either that or the builder set it to zero after his project was complete. around my parts 10,800 is a fair price if the truck is pristine condition. and i'm talking show quality here. i have been told that rhino linings do not hide anything. if it was dented before the spray job it will be dented after. also the stuff wont hold to rust. but thats just what i heard. i've never worked with it. round here a good looking, solid daily driver in the 67 to 72 year range runs about 5,000. give or take a couple of hundred.
