Good choice - however - consider this. I initially had Timbrens and they did the job of leveling and were good with the trailer. But when unhooked the timbrens provided a pretty rough ride since they are just a large version of the small stock bump stop. It was an ok ride on nice smooth roads but I felt the bumps on all the uneven roads. Switched to the airbags, still nice at leveling and now a smoother ride unhooked but then there is the potential of a air leak / bag blowout....
