For my 2017 Newmar Bay Star 3516 I noticed dramatic results. The issues the Sumo Springs seem to solve are due to overloaded axles. My coach was very close to GVWR from the factory, so the spring sag caused me to ride on the bump stops. The Sumo's raised the coach to the point where I no longer have that issue. They do help with side to side sway, I just drove cross country and aside from hating everything else abut the F53 chassis, the Sumo's were an appreciated upgrade.

Installing this Weekend

Sumo's are going on this weekend! Roadmaster sways as well. Excited to feel the difference.
Had a B+ Sprinter and the suspension upgrades were the best investment I made in 122,000 miles! All day at 75 and never break a sweat and rarely need 2 hands (and get 18 MPG).

Feedback coming once I get some miles on them.

I just put Sumos on the front and rear of my new 2017 Dynamax RV on the Sprinter chassis. Made a big difference in sway control and movement over uneven surfaces like pulling into a gas station.

I did the work myself and paid $334 for all four springs. The little rubber nubs they replaced did nothing but bottom out cushions. These stay engaged at all times and compress as needed to absorb shock.
