Here's the tow dolly me and my buddy built from scratch. It was the ultimate design of lightweight and compactness, yet exceptionally strong. Notice I speak of it in past tense, due to the fact that some idiot ran it over while I was going about 35 mph. It got a little mangled, so I had to leave it while we went to get the truck so we could through it in the bed. Then someone stole it! What a day.
