If you guys are having wandering and steering issues there are multiple threads on this forum that deal with that, seek and he shall find. One of the best things you can do for instant improvement is a Forest River spec'd alignment. I have the specs here: https://app.box.com/s/egdwsv5nefh2zub5n0rc7tw9m5izieov
In my case (2012 Sunseeker) I replaced all four shocks and steering stabilizer with Bilsteins and set my airbags to 65psi. Still had issues. It wasn't until I did the alignment that I was able to drive one handed, now this thing drives like a dream.
