My 3500 is a dually and I put Timbergrove airbags onit made a big difference. I almost bought the Roadmaster Active suspension. My understanding is these are awesome. A guy who works for me, at my recommendation, but them on his F250 and said it made all the difference in the world in everyday driving and also in pulling is Toyhauler 5th wheel. I will tell you the Timbergrove bags are by far my favorite bag I have seen. They are much better in my opinion than Airlift or Firestone. But that is personal opinion. If you can look at the Roadmaster you may end up with an entirely different truck out of this as it will preform much better all around. And in the grand scheme of things easier to install and less fuss after the install. If I could have put them on a dually I would not have airbags.
