Have also have one with many thousands of miles. Trips vary from very short to many hours and miles. We back in without disconnecting and we turn as tight as possible without issue. We used to have a minor amount of bounce but that was due to the trucks suspension not being as strong as was needed and it only happened on serious dips in the road. We only ever felt uncomfortable behind tanker trucks and their cylinder shape. No other wind or road condition has caused us to be fearful. It is the tilt head design and it sounds like that is the one that works.
It sounds like they are working with you to correct your issues and get you towing solid as a rock.
