prairiecamper, The Windstar jacks had a jacking plate that wit over a metal ridge un the underside of the van, the cap in the jack plate to fit over this ridge was just wide enough to also fit over the metal plate that is welded to the trl frame right between the wheels, thus providing a more stabel jack point. Dunnnc, I'd thought of also permanently mounting mine someway centered between the 2 axles, but was afraid that in the event of a blow out the jack would be ripped away and who knows what it might take with it. Guess I'll just stick with putting them between the axles when I get to the campsite.
