Question:

I have a 2023 Leasure Travel Van 24RL 2022 MB Sprinter 3500 chassis. The problem I want to solve is side to side sway. GVWR 11030 GAWR front 4410 GAWR rear 7720 GCWR 15250 I was looking at SumoSprings front and rear. I see SumoSprig has various models. What would you recommend? I also see Timbren makes a similar product. Thanks for your help

Hey Rick, thanks for the information! It looks like your 2023 Leisure Travel Van 24RL is a 2WD so that excludes the options for rear SumoSprings. Instead, I recommend the Timbren Rear Suspension Enhancement System item # TMBRSP35A. These are designed to stabilize your rear suspension and help you with that top heavy sway feeling.

For the front end, you'll be able to use the SumoSprings Solo Custom Helper Springs item # SSF-106-47, you were looking at. These replace your existing bump stops. Not only will they help with swap but they also do a good job of absorbing road shock.

Will you confirm that your motorhome is a 2WD?

Hey Rick, did you have a chance to confirm if your motorhome is a 2WD? I'm eager to continue assisting you with finding the right solution for that side-to-side sway issue.
