Daisy, Stabilizer jacks are used to prevent a parked trailer from bouncing on it's springs when the occupant moves around inside when parked. There are two types that serve the same purpose but are very different in design, construction, and price. Newer Airstreams are delivered from the factory with a set of four BAL crank down stabilizer jacks attached to the frame under the trailer, two at the rear and two near the front. The owner attaches a long handle and cranks the jack down to stabilize (not lift) the trailer when parked. A new set of those jacks probably costs $300 to $500 or more installed. The other approach is four small portable cast aluminum stackable jack bases with a long threaded vertical shaft. When parked, the owner places one under each corner and rotates the threaded shaft to raise the shaft to a point where the end contacts the (hidden) frame of your Airstream. The shaft is then rotated another half turn to snug up against the trailer frame and it will stabilize (not lift) the parked trailer. The stackable jacks can be purchased inexpensively from RV stores or catalogs. A caution about using the portable jacks, Airstreams have bellies enclosed by aluminum sheet which conceals the frame location. If the owner accidentally cranks up the shaft on the jack with the end pressing against belly skin, not belly skin with frame immediately underneath, the belly skin will be punctured. Neither would serve well to level a trailer on uneven terrain. The best approach would be to pull your trailer off of its parking pad, place 2" by 6" planks in the desired spot, then back the trailer onto the planks. If the situation calls for more leveling than that, it would be best to use a large commercial grade jack or jacks to lift and level the A/S, place boards under the wheels, then use stabilizer jacks to steady it.
