I’m waiting for parts now. Brought the RV home in the meantime. Will need the rear brakes and alignment. Optional is the shocks. They said KONI and Bilstein were about the same price which leads me to believe they are ordering the Bilstein. I decided against the helper springs. Very expensive and not sure if the other upgrades will help the ride enough. But the heavy duty Helwig sway bar was only about $500 with labor so I’m having that installed. A little over $5000 for all. It may be expensive but I know they do good work.
