I weighed our 2720 lightly loaded for camping ( no food or clothes, but everything else) and the tongue weight was 480 lbs. I later added a 2nd battery to the tongue, and with the addition of fresh water in the tank, I betcha I was close to 600 lbs. on the tongue when heading to the boonies. I don't consider that excessive for a Trailmanor. The heavy tongue weight, and the wheels placed a little further back are supposed to add to it's stability on the road. But.......if you don't have a WDH setup with that kinda tongue weight on lighter pickups, then that may cause the swaying. I would actually "tweak" my WDH setup on the road (add or subtract a chain length) to see what felt the best with the load I was carrying.....and I could tell a difference.
If it were me, I would by a WDH that you could add sway control later.....just in case the WDH alone doesn't work.
