On my second trip with my Itasca, I thought I had a handling problem. The MH kept pulling to the right while driving down to the Fl. Keys. I got down there, looked in my manual which stated the MH might need a wheel alignment if there are handling problems. I drove home a few days later and on that trip and a 1/2 doz or so others since then I haven't had that issue.I later assumed it had to have been the wind that was causing that pulling to the right. I can let go of the wheel and it will track straight (normally).
I'd suggest that anyone who has handling issues first get a wheel alignment before adding or changing parts. It could/should be a lot cheaper.
