Jeffrey R. Gullo –
When my wife and I head out in our 2023 Winnebago View we are looking for the best ride we can get. I don’t like swaying back and forth in crosswinds or leaning in turns. And we try to miss every big bump in the road but that is not always possible. After 18 years and 2 Sprinter Class C motorhomes without doing any suspension upgrades, we decided to try front and back SumoSprings. I chose the blue front and black rear SumoSprings and Wow! they give the RV a more “planted” feel and a better ride without increased road noise or stiffness.
I would absolutely buy them again. They have increase our confidence alot. My goal is to have a motorhome that drives more like an SUV. The SumoSprings along with new rear Fox shocks have given us a much improved ride. We now feel more relaxed when driving in cross winds and I can’t describe how much better it feels to turn without leaning. Happy driving, hope you enjoy the road as much as we do.
