Hi Stephan, happy to help!

I’d start with the Hellwig Adjustable Rear Anti Sway Bar, part # HE73GR. It’s a great way to address the side to side movement you’re feeling at highway speeds, especially from wind and passing traffic, and it will help keep the truck more planted and predictable. Hellwig is also a very reputable name when it comes to sway control, and this bar is designed to fit even if your truck has a lift.

Since the Project M is a relatively light camper, I’d pair that with the standard duty SumoSprings Solo Custom Helper Springs, part # SSR-312-54. They’ll add support to the rear suspension and help minimize sag and sway without going overly stiff for a lighter camper setup.

Are you mainly trying to improve the highway sway, or are you also noticing much rear end sag when the camper is loaded?
