Installed them on a Ram 2500 to control the jumps generated by a 5 wheel RV. You've definitely achieved it. The problem I've noticed is that the truck now only sags an inch meaning the nose of the RV is above level causing any unbalanced load to cause the RV to roll over rough roads or Bumps "hangs". Installation was fairly easy - place the struts on the brackets, then jack up the body with the hitch frame just enough for the socket and extension to fit in the jack housing. They do what they're designed for, I'm just not sure I can leave them installed if I can't get the camper to push more without exceeding the payload. The airbags may need to be swapped out to adjust, but I still want to experiment with where we put things to try and get them to work at all. They do not interfere with normal driving, except perhaps when crossing speed bumps, as there is a centimeter gap before contact. The 4 star rating doesn't reflect the product so much that it doesn't fully work in my situation.
