The first truck to us the hydraulic body mount was the gmc sierra 1500 hybrid only sold in California for a few years. I own a 2012 hybrid sierra (yes they do exist) it has one on the passenger side of the chassis. It helps the specially tuned z85 suspension package perform better over rough and choppy roads. The mount was used extensively on the next gen trucks starting in 2014 I believe all 1500s 2500s and 3500s use them now and more than one.
