An Italian OMFB double diaphragm pump works the 3x12-inch single-action cylinder that raises the bed, and just ahead of it is a 2,250-pound Butler jack. Bolted to a tray under the bed is a clevis, easily swapped for the 2-inch ball coupler installed. Both are swiveling and greaseable, just like the axle pivots. An unusually narrow tongue (about 26 degrees) can allow jackknifing the trailer to over 90 degrees, depending on tow vehicle width and towing attachment dimensions, even on the jack's side.
