Recommended Suspension Enhancement For 2021 Dynamax Motorhome On Mercedes-Benz Sprinter 3500 Chassis

Question

Question:

I have a 2021 Dynamax Isata 3 24FWM motor home on a 2019 Mercedes Benz 3500 chassis. It has a Helwig rear sway bar and Bilstien shocks. I normally load to capacity 11,030 pounds and tow a 3200 pound car. Which Sumo springs do you recommend for the Motorhome in this configuration?

For your 2021 Dynamax Isata 3 24FWM motorhome built on the 2019 Mercedes-Benz Sprinter 3500 chassis I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-338-54 which have a 1400lb load capacity which will do great at supporting the rear suspension while you are towing your 3200lb car, but will not negatively affect the ride quality when you are loaded lighter.

If you would also like to add suspension enhancement for the front axle to prevent sway and further increase your driving experience I recommend the SumoSprings Solo Custom Helper Springs - Front Axle # SSF-106-47.

I included videos for both of the products mentioned for you to take a look at.

For your 2012 Winnebago 24M on Mercedes Benz Sprinter 3500 chassis, I recommend the Timbren system consisting of the Timbren Rear Suspension Enhancement System #TMBRSP35A and #TMBFSP35. Timbren is a stiffer support spring than the SumoSprings, so you…
