I'm 800 miles from my vendor. Decided to start with new shocks. Purchased Belstein's at recommendation of my local mechanic, who also offered that looking at the undercarriage, I shouldn't need anything. When we pulled the shocks (still new), one was completely failed. Could extend and contract without resistance. Went ahead and mounted both new Bilstein shocks. Drove like my new buick!! Check shocks first. A Chevy G4500 shouldn't have handling issues if everything is working as it should.
My next item.- Bilsteins.
I believe all class C motorhomes should be re=aligned. I say re-aligned because they are all set at the factory the same- regardless of weight added or vehicle intended use.
Realigned after broken in that is- once everything settles in.
