Claim 0:
1. A trailer anti-theft device, comprising:
an interposer having a solid square metal bar having a coupler interface, a tongue interface, and an interposer stop, the interposer is adapted to couple to a trailer;
a tongue adapter adapted to couple to a tongue of the trailer;
a hitch pin having a hitch pin shaft that passes through an interposer aperture and an adapter aperture, the hitch pin prevents the interposer from sliding out of the tongue adapter;
wherein the interposer is detachably coupled to the tongue adapter and is retained by the hitch pin in preparation to adapt to hitching the trailer to a tow vehicle for towing;
wherein a coupler of the trailer is coupled to the interposer;
wherein the coupler and the interposer are stored away from the trailer to deter theft of the trailer;
wherein the interposer and the tongue adapter include a plurality of additional anti-theft features such that a substitute coupler will not fit in place of the coupler that was removed;
wherein the coupler interface is attached to the coupler such that the coupler interface is positioned on the coupler where the tongue would ordinarily be positioned extending rearward from the coupler;
wherein the coupler is welded to the coupler interface;
wherein the coupler interface and the tongue interface are located at opposing ends of the interposer with the interposer stop defining a boundary between the coupler interface and the tongue interface;
wherein the interposer stop is an enlargement of the interposer surrounding the interposer at a boundary between the coupler interface and the tongue interface to limit a insertion distance of the tongue interface;
wherein the interposer includes a blocker slot and the tongue adapter includes a blocker plate that aligns with the blocker slot such that the interposer slides into the tongue adapter without interference;
wherein the tongue adapter includes an upper collar and a lower collar;
wherein the upper collar is a boss located on a top of the tongue adapter, the lower collar, on a bottom of the tongue adapter;
wherein an upper collar aligns vertically with the lower collar if both are present;
wherein the upper collar includes a collar clip aperture and a retention clip is inserted through the collar clip aperture in the upper collar and through a hitch pin clip aperture in the hitch pin shaft in order to secure the hitch pin;
wherein the interposer aperture is an equal sized diameter as the adapter aperture and the diameter of the hitch pin shaft is smaller than both the diameter of the interposer aperture and the diameter of the adapter aperture;
wherein the hitch pin is removed and the interposer is decoupled from the tongue adapter when the trailer is stationary; and,
wherein the adapter aperture and the upper collar is positioned such that an adapter aperture aligns with the interposer aperture when the interposer is coupled to the tongue adapter.
