I have put over 100,000 miles on my Ford dually and Lance 981 on all kinds of roads and conditions. As has been mentioned, a rubber mat is manditory, forget the spray in liner. I have used Happijacs with zero issue, but I am sure that the Tork Lifts are just as good. I use the turnbuckle on rods and they are simple and work just fine. I do not really see paying the extra $$ for the fast guns. It only takes a few minutes to install and adjust the turnbuckles. Although I have airbags and extended bumpstops, I highly encourage you to invest in a set of the Tork Lift Stable Loads, both the bottom and top ones. With these, you probably will not need airbags and will have a reliable and trouble free ride. The best advice that I can give to a new TCer is Keep It Simple.
