I originally used the SSR-116-47 on my F-150 but noticed a much harsher ride when unloaded. I switched to the SSR-116-40 and it is night and day better unloaded and much better than stock with a large payload. The 40’s assist with the load without changing the unloaded ride characteristic. With a 1500 lb load, I have no body roll and the entire truck/fifth wheel combo feels stable and solid. This is a great product from a fantastic company with great customer service.

Easy installation took the sag out when empty rides well haven’t had a chance to try it under load yet but I’m confident it will perform as expected
