As with most things an extra set of wheels helps with the ride and control when turning. Even with a normal trailer, as a few of the guys have mentioned, the control for reversing is so much better. We started with a camper trailer and it was a pig to back, but don't have any issue with the 18ft dual axle, as it goes where I want it to. I had to reverse through a single roller door into the back yard at the old place, and was able to get it first go swinging in from the street, as the extra wheels helped it step over there kerb, where a single axle would fight you all the way.
