I towed a refurbished roller VW chassis (without a body) with a VW tow bar a couple hundred miles on the PA Turnpike. (I did make up a rear light bar with a 2 x 4, cheap trailer lights and duct tape ) Stopping at a rest area, a PA Trooper shows up and discussing the towed chassis, once I pointed out that I had (A) lights and (B) four good tires that was the end of the discussion.
