Top 3 Essential Upgrades for the Mercedes Sprinter 3500!

In today’s video, we’re working on a 2022 LTV Unity Class C motorhome built on the Mercedes 3500 chassis. While this chassis features precise electric rack-and-pinion steering and a solid diesel powertrain, it still struggles with low-speed sway, rocking, and rolling—especially in crosswinds or when passing large trucks.

We’ll walk you through the weaknesses in the stock suspension setup and then show you how our SuperSteer upgrades (rear track bar, upgraded sway bar, and adjustable rear shocks) transform the driving experience for greater safety, comfort, and control.

If you own a Sprinter chassis motorhome, this is must-know information for improving stability and enjoying safer and happier driving.
