I know of only one shock absorber that handles the heavy duty application of a loaded motor home, but also reduces the jolts felt from the expansion joints in the pavement. They have been used in the largest of class-A motor homes for many years, but just this year came out with one specifically made for the E350/E450 cut-away chassis.
HERE THEY ARE but be prepared for sticker shock. Nobody sells anything like them. I'd buy them for our rig but I am not made of money yet. I'd consider getting just the rear two but still can't justify it at half the cost.
