Abstract: Hitch mount assemblies include a trailer hitch receiver, a hollow sleeve inserted into the trailer hitch receiver, and a hitch mount inserted into the hollow sleeve. First and second planar end surfaces of sidewalls of the hollow sleeve lie in a common plane that is oriented at an acute angle to a central longitudinal axis of the hollow sleeve. Additional hitch mount assemblies include a trailer hitch receiver, a hitch mount, and a hollow sleeve that includes a first L-shaped elongated member and a complementary second L-shaped elongated member. Further hitch mount assemblies include a trailer hitch receiver, a hitch mount including an elongated bar inserted into and extending from the trailer hitch receiver, and a hollow sleeve at least substantially fully covering the portion of the elongated bar extending from an opening of the trailer hitch receiver.
