We had AirLift 1000 on our 2015 RAM 1500 and it was great, but we were towing a fifth wheel then and the payload was an issue (we were within limits) as was squat. After lightning consumed that truck and RV, we bought a 2019 RAM 1500 with 1000 lbs more towing capacity and more payload and our Lance, which is 1000 lbs lighter than the old fifth wheel. I am in the process of realigning the same hitch Jonathan has. Once that’s done I’ll probably get the airbags installed again. I see no downside and I do want to stiffen the coil springs in the rear. The RAMs have been great trucks (although a lightening rod would be helpful) with a dry smooth ride, but the downside to the coil springs is the sag under heavy loads.
