I bought my windsport 31S in June 2015. It drove so horribly I wanted to get rid of it immediately, but after researching on the forums and the Internet,I found several things that can help considerably.
I have installed the safety plus system in the front , rear track bar, and sumo springs in the front. Also the five-star tuner. The driving experience is considerably different , it went from a white knuckle ride and my wife didn't even want to be in the RV. Now with these changes it is an absolute joy, I sit back and relax and drive with one hand.
