I just bought this and thought I'd share. It's the EzStorHitch. The First and Only, Complete Hitch and Spring Bar Storage System on Market. It's on Amazon for $150. You can store your WD bars and hitch in the holder that bolts to the frame next to the propane tanks. The hitch, when in place locks the bars in and the hitch can be locked with a pin lock. It gets the hitch out of the truck bed and I'm all for that. My F350 bed is too high for this old fella.
