Solved my issue with trailer jerking truck around.
I tow a camper with 700lb tongue weight in my Nissan Titan, and would make drives uncomfortable because unless roads were perfect, the trailer would cause a jerking sensation in the truck. With the ras system, it has eliminated 85% of the jerking sensation, it was immediately noticeable. It also leveled out the suspension while towing, where as before it was squatting a little too much for my liking. When not towing, the rear sits an inch higher than factory. I found the driving when not towing unaffected, or at least it doesn’t feel worse than before.

sacrificed some ride quality
Definitely adds to tow capacity and stability. Ride while not towing suffered quite a bit though.
