For your motorhome built on a 2018 Mercedes-Benz Sprinter 3500 we have great suspension enhancement kits available but none that use air bags. Instead the kit I would recommend is the SumoSprings kit part # SSF-106-47 which is similar to the Timbren but won't be as harsh of a ride. This will help brace the rear suspension which will help the vehicle ride better and not have quite as much body roll.

If you haven't driven the motorhome yet I'd recommend doing so first. There's no rule that says you have to install suspension enhancement but doing so will improve the ride quality.

Correct, the SumoSprings Solo Custom Helper Springs part #SSR-338-47 will have a softer ride than the SumoSprings Solo Custom Helper Springs part #SSR-338-54 as it's made of a softer spring. That said, the latter will also provide more support.…
