ABSTRACT:
A receiver hitch-mountable utility cart has a support frame for supporting a payload, a hitch arm rigidly attached to the support frame, the hitch arm shaped to engage a receiver hitch bar of an over-the-road vehicle, a wheelbase assembly with wheels for transporting the cart with the wheels on the ground, and a user-operable translation mechanism connecting the wheelbase to the frame, enabling the frame to be raised and lowered relative to the wheelbase by operation of the translation mechanism, such that the cart, in an uppermost position, may be aligned and connected to the receiver hitch bar of the over-the-road vehicle, and the wheels may then be retracted to carry the cart entirely on the receiver hitch bar.
