Talked to my local trailer guy today about adding air bags to my truck. He said with the 1 inch gain in the back I couldn't run standard airbags & was suggesting supersprings. Is this true. I know Carli has the long travel bags. The guy also said leaks were a common occurence with air bags, this I don't see how with all the rigs with airbags on the road. Any help would be Greatly Appreciated on the subject.
