OP- They manufacture a cone shaped stand that has a hole in the top for the jack tube to sit in. It's made of tough plastic and is designed for the tongue jack. The only drawback is you have to remove the foot pad on the jack. If you don't want to do that, then use wood or the lego blocks to shorten the travel distance for the jack.
