Just replaced my Superglide with the Andersen mounted on ISR. First trip out noticeable bucking when accelerating through a mildly bumpy intersection. Noticeable mild bumping going down the highway. Superglide was smooth as silk on same highway at highway speeds. I love being able to pull the Andersen out in a couple minutes. Lightweight frame is so nice. Not so sure about the ride quality. Regular bed Chevy one ton pulling a 3120.
