We run a F250 2020 on a lotus 19.5 off road, the vehicle when out on the back roads holes dips and dives would push and pull you around like riding a buckjumper. Another user off the Oz Glide said you need to put one on your van you will not know yourself. So we purchase one and i have to say, its a new F250 no pushing and pulling wish we had done it 25000klm ago.
