Most shock threads mention the Bilstein or Konis. Per thread mentioned above I went with the Koni and am really happy. I have a smaller, 27 ft Forester, and it handles pretty well. Biggest improvement was the ride and sway. With 3000+ miles now, the Koniís eliminated the harshness. Still feel the bumps and countless potholes, but it doesnít rattle the camper as much. I wish I had upgraded sooner. DW is happy too, so happy camper!
