REVIEWS FROM THE ROAD
George Stark's 2016 Winnebago Sightseer 36z with SumoSprings front and rear. This is what he had to say about the upgrade.

"I started with the fronts — such a drastic change."
"Before SumoSprings, my RV sounded like a rattle trap going down the road. I tried a front end alignment and had the tires trued for roundness. Still didn't fix it. SumoSprings have literally taken little vibration bumps out of the equation completely and the feeling of rollover every time you make a turn. Before, I couldn't take my eyes off the road to adjust the radio."

"To me, it feels every bit as good as liquid spring my friend has that on his 36 footer, and that's a $14,000 spring unit."

"The engineering is really set up perfect on SumoSprings. It appears a lot of thought was put into it. I was concerned it would stiffen the ride too much, but that was not the case. I'm pleasantly surprised! The SumoSprings act as much like a shock absorber as they do a spring. They're a fantastic innovation for a loosey-goosey chassis."

"It's perfect; definitely takes the rock out of things. 80% of the issue was in the front — the rears were the other 20% that was missing. With them, I've noticed porpoising is virtually gone."
