You can see the trailer jacks on the back of mine. Pull the pin, flip 'em down into position, and it's a drop leg too. Adjust as needed. They make a LOT less noise than I thought they would going down the trail.
Those look cool, but I don't think they'd work for me, as I wouldn't be able to open the tailgate, and mine is also a dump bed utility trailer, so those might get in the way there as well..
