Recommendation for Reducing Rock On 2016 Forest River Sunseeker Mercedes Chassis Leaving Driveway

Question

Question:

I own a 2016 25foot Sunseeker MB 3500 RV. I find it rocks to side pretty dramatically when you pull out of a driveway. I am wondering does it need new rear shocks or hard rubber suspension cushions like Timbrens.

I recommend adding the SumoSprings Solo Custom Helper Springs # SSR-338-47 to your 2016 Forest River Sunseeker on the Mercedes 3500 RV cutaway chassis. These are a progressive rate spring that will help to absorb the rocking when pulling out of the driveway. The Timbren Springs # TMBRSP35A are a much harder rubber spring and will lead to more shock/bounce than absorbing the the compression.
