I prefer the paint,as original, over a liner.I think it looks better,sweeps/washes out easier,and its' easierto drag heavy objects over a smooth, hard surface. I can and often haul as much bed weight loads as a Ford F-150 is capable of and love the low reach-over-the-side Camino design to unload over a conventional pick up. Its' a truck-the title says so-bed scratches don't bother me.The factory put a heavy duty--what--zinc coating?-under the paint so the bed would not rust when scratched.When a Camino bed rusts out its' from the bottom from road salt.If you wanted to you could make a full-size paper or cardboard template of your bed floor for the wheelwells,etc.Then lay it down over a thin ,light sheet of plywood or paneling to cut out.Or buy the cheap light ribbed rubber from ,like Lowes-but weight it down when you need it-the paneling,too--they can suck out over the road.Your bed pics just seem to need a prime and paint.
