My 2018 GMC Sierra 1500 with Ovrlnd Camper is my daily driver. Even though I have Zero build-out in mine, the extra 400lbs +- makes a difference in the ride. I just added the rear Sumo Springs and these are great! No crazy swaying around corners, and an overall better ride. Best of all they are inexpensive and about a 30min self install. These replace the original bump-stops. The original stops were about 3 inches from touching the axle.
