Oh ya, thanx for posting this idea!
The gears in my head are churning as to how I will incorporate/fabricate one of these onto my car hauler trailer. I'm thinking of some sort of removable setup that hooks into the 2X4 pockets on one of the sides forward of the axles.
Everybody inspired by this post should post your fabrication results on this thread! I will once I get something done.
