This system, along with Dexter's leaf springs, came stock on our 40' 2016 Cedar Creek 5th wheel. Love the suspension. Our trailer (GVWR 16,500lbs) tracks so well, including on rough roads, e.g., under construction. It's also apparent in how items in the trailer that are left out rarely move. We have also had a blowout (45mph, on a mountain highway, in a curve, front axle, driver-side tire) and the tracking and control wasn't affected. Highly recommend.
