Sumo springs. Anybody got them?
Our friends just bought a new Tiffin gas. It didn't come with the Sumo upgrade. Are they worth the price? Also, do they replace the factory springs or are they an add in?

I had them installed on my 2014 tiffin 36LA. I drove the coach one year without them, this year with them. they do two things. one they stop the side to side motion, and they soften up the ride.
