Rear Air Ride Suspension

[bhammer]

Has anyone installed one of these rear only Air Ride Suspension setups? I saw that they make rear only kits, I've heard that they are jumpy when riding in them, like they are too stiff. I just want to be able to level out the stance of my truck, however, I do a lot of towing and want to be able to tow and load the bed without straining the suspension and I've been told Air Ride is the best for this. Is this a hard install? Is the upkeep on these a lot? Any info would be greatly appreciated.
