My wife and I test drove the Thor ACE 27.1. I too thought it wandered on the road and when a large truck went around us it pushed me to the shoulder of the road. We ordered a new ACE 30.1 five weeks ago, was told it will take up to 10 weeks to get. From what I've been reading you can change the sway bar mount to the other hole and this helps. I have also read that you can buy an after market sway bar to help even more with this problem. Since I have one on order I guess I will deal with it when I get it....
