I cant say the towing did that. I think the springs might have been rebuilt, that is Ive heard some places reheat old ones stretch them out and sell em as new ones. The trailer I towed was one trip with a car dolley towing a Cavalier, and two trips with a light coleman pop up trailer. I was really pi$$ed off that this happened twice in such a short period.
