We use theAirSafe with a Reese Dual Cam system.
Obviously, weight distribution is a minor factor with a 3/4 or 1 ton truck. These trucks have plenty of capacity to tow any Airstream.
The concern is a soft ride for the trailer. I tension the WD system enough to provide a good anti-sway action from the cams and call it good.
30k plus miles and we are happy. No popped rivets, door still shuts easy on our front bed unit and no sway or "bow wave" reaction.
The Air Soft made a noticeable improvement in our towing.
