Abstract: A removeable base plate accessory member for the support jack leg on a trailer hitch providing a flat base stand for a trailer when the trailer is being parked and left in a particular area. The base plate member is easily attachable to or detachable from the support leg and may be adjusted to vary the relative height or distance between the accessory's base plate and its attachment connector leg used to attach the base plate to the support leg of the standard type jack found on most trailer hitches. The preferred connector (FIGS. 2 and 3) includes a pipe section with a bottom plate welded to it with a centrally located opening with a nut welded to the bottom plate, with the base plate member having a vertically extending centrally located threaded stud threadably engaging the nut.
