I would never use a bottle jack on an AS IMHO. The "Trailer Aid" is much safer and you don't have to worry about the jack failing or trying to get it in the "exact" spot on the frame. Also, if you do have a flat, most times you can't get the bottle jack under the best location. If you must use a jack, a good sizzor jack is much safer and better, easier to handle and has a broader lift than a tiny bottle jack.
