NEW Dodge 2013 Ram 3500 4x4 -> ride is horrible! What to do?

One difference is the shorter wheel base of your truck compared to NChaulers long wheel base. Another is the parking lots, err freeways in your area. Being from S Cali those concrete freeways can get pretty rough. I traveled the I10 through the Ontario area and swore I was catching air in the rear. Play around with the PSI and add some weight. All the trucks around here carry hundreds of pounds of sand in the bed in winter for traction and I notice the ride difference.
