ABSTRACT:
A guide to aid in attaching a vehicle to a trailer. A hitch guide is comprised of a cross member 20, a forward member 30 adjustably attached to cross member 20 mounted substantially perpendicular to cross member 20. Forward member 30 has a second cross member 40 adjustably attached thereto. Second cross member 40 is mounted perpendicular to forward member 30 and thus substantially parallel to cross member 20. A wire 22 can be provided on cross member 20 to be located directly underneath the ball of the hitch. Forward member 30 is then adjusted to touch the oustide of wheel 62 and the towing vehicle is moved backwardly until wheel 62 just touches the second cross member 40.
