If Fulton, Attwood, or some other jack manufacturer would simply listen, I think this idea is worth considering.<br />A conventional screw jack with a flat steel foot, rather than a wheel, could be temporarily attached to the side of a single axle boat trailer next to the tire needing replacement. Attachment would be via a cylindrical sleeve (hollow metal tube) that slides into a mating tube welded to a conventional mounting plate that most jacks already have attached from the manufacturer. The matching plate would be affixed with a slightly larger cylindrical sleeve into which the mating part on the jack would fit and be held in place with a latching pin or snap ring. The jack could be easily removed and stowed away when the task was completed. Isn't this far safer than attempting to maneuver a scissors jack from the automobile, which probably won't fit right anyway, up and under the trailer, on uncertain terrain, with eighteen wheelers whipping by your six at about sixty five mph? Does anyone think this is a reasonable idea? I'm ready to fabricate the concept if some trailer accessory manufacturer can't get up the gumption and try it themselves. I guess they're all afraid of product liability issues.
