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.

Hello Ed, Personally, I like the SumoSprings better. I have recommended them to many people for the exact reason you are looking to add them, to get some color back into those white knuckles. I only recommend the Timbrens for someone who is under a…

I absolutely recommend a proportional, inertia-driven braking system when flat towing any vehicle, much less a heavier one like your Ram 3500 because of exactly the reasons you mentioned. These types of systems don't rely solely on the brake…

Depending on what kind of toilet you have the model number may be printed on a sticker that will be on the right side of the base of the toilet. You can use a mirror or your cellphone to view the sticker if it is hard to get to.
