Made this about '82 as I didn't like continually renting them. Hauled three 20' rectangular tubes under my '77 Ramcharger from the iron shop. Removing two bolts and two pins I can lean up against a wall out of the way. Rolls between wheel wells in my pickup. A little on the heavy side but has no trouble with a 440 with trans attached. You can see by the picture it's dual purpose. Gave the kids something to do one day during summer vacation!
