I had one installed on a previously owned Newmar BayStar 35' class A gas coach. Great addition, but it must be proper adjusted during a test drive for it to work properly. The tech and I went for a drive with him driving and he got out a couple of times on the side of the road to make minor adjustments. Once adjusted properly very much more comfortable steering.
I had a SafeTPlus installed on my 2015 Winnebago 27Q Class C...along with other additions...and well worth it at the end of the day. Good to go until the booty call.

If you have the Spartan chassis, it already has a double steering stabilizer. You can see it by kneeling down and looking under the front.

I have one installed on my 2013 Itasca Sunstar 26HE. I have done a lot of suspension upgrades (air bags, anti-sway bars, rear trac bar) including the Safe-T-Plus. In my opinion, it does help with the steering and I would do it again if I bought a new motorhome.
