Years ago I builr a pair of air bumpers for a 1977 Renegade.My family owned 1000 acres in Cannan Valley West Virginia ,It was very remote rugged area in eastern West Virginia.I wanted to have air for tire inflation so I bought some 3/8 4 inch square stock and welded brackets for mounting to the frame and endcaps with a schrader valves to load air in them.On the backside I put a shut off valve with a fitting for my air hose.I could load them up with 160 lbs of air which was enough to fil a tire from each bumper.Later I welded tow hooks on them . Just looking at them it was not apparent that they each held 160 lbs of air.
