Question:
What’s the best sumo set up for a 2007 30 ft Winnebago RV? E450 No towing, light pack without water in reservoir most trips. No generator. Solar with 2 batteries and inverter in back. Trying to soften the ride as much as I can. New bilstiens installed. Sway isn’t a serious concern currently.

Hello Gunnar,
The first time I answered I misread the question, for some reason my eyes saw that sway was a concern. For your 2007 30 ft Winnebago RV on a E450 chassis the SumoSprings are going to be your best option for the smoothest ride. Given your load the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-107-47 would be the best fit. The yellow ones would be great if you were more worried about sway, and were carrying a heavier load. The # SSR-107-54 are rated for 2,800lbs, and the # SSR-107-47 are rated for 1,500lbs resulting in a smoother ride. They will be a great addition to the blistens that you already installed. I included a review video for you to check out.
