Duster Towing

33IMP, I had a setup like you pictured for many years & flat towed many cars that way. At 2 day races, we slept in tents & if it rained, we slept in the seats. AH, the good old days. LMAO
We used that setup to flat tow to riverside raceway before it closed in the eighties, and bakersfield for the firestone/centerline finals (havent used that description in a few years, lol). Used an ez-up and pool mattresses in the pickup bed.
Funny thing, it would work just as well today, and be easier to set up. A light battery impact and an aluminum floorjack would be easier than our old 80 lb floor jack and star wrench. That star wrench got turned a bit, what with 3"studs on the race car... kinda miss old days, and being that young....
