When I lifted the Ute I added a 50mm block to sit the jack on, the block is a good 250mm wide and provides a good base plate for the jack which is a must, the standard jack is good for concrete flat floors but on the road you should always carry a large flat base plate, scrape some dirt , lay base and mount jack, with a lift a fatter plate is needed, sometimes depending on the point on the vehicle they have as jacking points, a 25mm bit of pine is good to fit between vehicle and jack, less chance of slipping..... Jacks are designed by a chair borne warrior and an algorithm, flat, solid ground is rare, it pays to be ready..
