I like the ride of both the 2500 and the 3500 but the 2500 was better for me. The big thing for me was the shifting of the Aisen and the fact there are no tunes for it, If I could have found an SO 3500 with what I wanted on it I would have bought it instead of the 2500. I usually end replacing the suspension with Carli anyway. For what it's worth, I seldom tow.
