The hitch is original except the Minneapolis AS dealer replaced the forged hitch bar when they set it up with my TV about 15 months ago. The newer Yukon/Suburbans have the hitch sitting much higher. My trailer still runs a little hitch high going down the road. This hitch does not have the dual cam sway control. It uses the trunnion bar & chain set up.
What you have described here is only a Weight Distributing hitch. The hitch with only bars and without cams and trailing arms has no sway control function.
Additional the older Reese hitch heads that were not tile adjustable have a very limited arange of adjustments and over time the trunnion cups ware reducing that range even more.
As for riding tongue high that says the head either is set too high in the shank or the shank does not have enough range to lower the head enough.
When an Airstream is riding tongue high it has a heaver tongue weight because of the type of axle used.
If a dealer set you up with this way find another dealer.
