The present invention provides an open sided flip-down leg for a trailer, or a trailer tongue, or a conversion kit thereof, being secured by a hitch pin in a transportation mode, pivots to and is secured vertically, by a catch to a front angle brace, in a storage mode. A rear jack housing, utilizing gears positioned therein, deploys a triple hinged support base with a castor wheel, mounted on its front side, which raise a tongue/frame upward facilitating attachment or disengagement of a tow bar to a towing vehicle, or for other purposes. Retraction of said hinged support base, and said castor, causes said tongue/frame to be lowered to a point of contact between said open sided flip-down leg foot plate and a ground surface. A 100 manifestation presents a flip-down leg of hollow tube construction, housed inside and moving through an open under side of a tongue/frame to a vertical position, secured by a catch to a front angle brace, enabling its jack ground contact plate to be ratcheted or screwed down or up, utilizing an elongated square drive socket, causing a tongue/frame to raise providing assistance in attaching or detaching a towbar from a tow vehicle. "Y" configured trailer tongues having a flip-down leg at each side, may also utilize them leveling a trailer frame. A 200 manifestation presents a hollow deep tube flip-down leg, secured vertically by a catch to a front angle brace, having sufficient lower portion capacity to wholly or partially house a conventional or modified, retracted top sidewinder trailer jack, which may be deployed to raise the tongue/frame and provide a castor wheel for mobility.
