As many of you know my dad had an RV sales business back in the early 60's.
He was towing small campers, and up to 17' lightweight travel trailers. Towing them with full size cars. At first he would tow on just the ball and then moved up to an Equalizer brand WDH. He could not believe how much better the tow was even with the smaller 14 to 15' travel trailers. Even in the back seat of the sedan's as a kid I could feel the differences when the 18 wheelers passed by. The WDH is pure genius. It's almost a crime not to use one.
Airstreams..... The best towing trailers on the planet!
