Not a hoist but a hanging bar for skinning.
Two 1" square tubes bolted to the truck bed through existing holes, one 2x4 and some pipe. Sets up in about 30 seconds or less.
Pretty creative, and portable for places with no trees to use for hanging poles. How sturdy is it?
I've never tested it for maximum weight but I think it would hold a gutted elk.
I think you'd have to be careful with a heavy load that was anything other than hanging straight down..
If you wanted to lift a large whitetail for instance and fitted it with a pulley, and then rigged up a winch to the back of the pick-up bed, I suspect the angle of the pull might warrant a bit of extra bracing..
Obviously, thats a deviation from its current intended purpose, for which it looks fine..
