All three SumoSprings kits fit your 2018 Ram Promaster 3500. The difference is the capacity of each. The # SSR-313-54 is the highest rated at 2,800 lbs, the part # SSR-313-47 is 1,500 lbs, and the # SSR-313-40 is 1,000 lbs.

Due to the weight of your motorhome I'd recommend the highest capacity kit # SSR-313-54 which will make the biggest difference.
