I've been running RideRite airbags on my 08 Taco since putting the Finch on my truck in 2009. I also had the Toyota 4 leaf TSB added to the truck. I have never had a single problem with this set up since installation.
The install was easy if you have a basic set of tools, a floor jack, some beers, and a little patience. The airbags are usually "no drill" depending on the year of your truck. Which means you dont need to drill a hole in your frame. It was EASY.
When I have the camper on(80% of the time), or if Im towing my 6000# boat, I inflate the bags to 50psi. It keeps the truck level and rides just fine. The only "roll" you will feel is when you are trying to take a turn faster than you should be with a 1000# camper.
Otherwise, I take the camper off and keep 5psi in the bags to keep them exercised.
I did add some FOX Shocks with reservoirs since I tend to do a lot of dirt roads and off-roading. If you add a big leaf package, the truck will probably ride real stiff in the rear when your camper is off. I believe I paid $325 for them. Why not have the best of both worlds with the airbags..?
