Looking for help in improving the ride on my RV

Gary, empty, the MHs ride great. Our first trip with ours, we hardly had anything in it except for basic cloths, utensils, water and gas. We actually commented on how nice it rode on a known road the first trip, but we accumulated more and more "necessary things", the MH quickly settled into the springs, and a rough/harsh ride developed. We had maybe 3/4" between the bump stops and the spring perches and the MH was not overloaded. Hitting the bump stops is what gives the rough ride.
