I used to own an 2010 RT Audio and Convenience. It was a great machine, had a few issues but all fixable and out the door. Decided to trade because I was tired of the color (Gray) and liked the new blacked out bottom, bigger wheels and the new frame. I had to get the ball joints replaced since I noticed that it was very "squirmy" on the road. It made a BIG difference. Yes, you can tell the difference on the 2010 and 2013 maneuvering. The 2013's shocks are different since they need no adjustment based on weight (the '10-12's have the 1-5 setting) and the setting are a tad higher.
As far as handeling: It hugs the road a lot better. I recently came back from Hot Springs and went to both the North and West Mountains which are very curvey. I love the response on it. I even made the comparison on my wife's RS-S and you can that the response on the curves is more settled and compensating.
I am loving the change so far!
