Sway bars, steering shock

I recommend a good steering stablizer like a Blue Ox Tru-Center (what I have) or a Safe-T-Steer with optional remote re-center (not offered when I had mine installed)

Also at least one track bar if not two (Rear and front in that order ( I Have a front one plan on the rear... Some day)

Sway bar may or may not be needed depending on the one that is already there.
Mine did not need it .

There is alot of talk about this on the Thor Forums www.thorforums.com/

Myself on my 29.3 ACE have found no need to adjust the sway bars or add the safe steer type of system. It takes alittle getting used to, and yes driving with a strong cross wind is not fun. Remember this is a big box going down the road.
