Back in 1990, Bob Sage, President of Travel-Lite purchased a 1 ton truck with a service body on it. He thought would be the perfect tow vehicle and it was except for one thing; it had a very stiff rear suspension which in turn had a tendency to break and crack the welds on the tongue of his trailer. This inspired him to weld up a hitch that had a coil spring on one end, a pivot in the middle and a hitch ball on the other end. And with that, the welds stopped cracking, the trailer rode better and towed better. Eventually, the truck got old and he sold it along with the hitch.
In 2000, he found himself back on the road delivering trailers, wishing he had that old hitch back. He realized if he had this problem of a jerky bumpy ride, that most people towing trailers also have the same problem. So he set out to develop a new and better hitch. The first few attempts worked but were not adjustable for various loads. After three years of testing and improvements, it was decided to use an air bag as the cushion, now the user can adjust air pressure for various loads and the bumpy, jerky ride is gone.
