Nesting stabilizer

A stabilizing apparatus connectable with a hitch receiver for a vehicle, the hitch receiver having a protruding ring at one end, the stabilizing apparatus limiting free-play movement of an accessory attached thereto, the stabilizing apparatus comprising:

• a hollow base-body insertable into said hitch receiver, said base-body having a mounting plate attached to a non-insertable end of said base-body;
• a flanged collar attached to said mounting plate, said mounting plate having a center hole;
• a T-shaped sliding pin barrel formed of two intersecting cylinders, one of said cylinders having a through-hole and arranged transversely in said base-body and having protruding pin barrel shoulders riding on longitudinal channels arranged on opposite sides of said base-body, the other said cylinder having a threaded hole with one opening facing an inner face of said mounting plate;
• and
• a threaded draw bolt insertable through said center hole of said mounting plate and screwably engageable with said threaded hole of said other cylinder of said T-shaped sliding pin barrel so as to force an interference fit between said flanged collar and said protruding ring when said draw bolt is rotated in said threaded hole so as to reduce free-play movement between said stabilizing apparatus and said hitch receiver whenever a securing pin is inserted into opposing holes in said hitch receiver and said through-hole in said transverse cylinder of said T-shaped sliding pin barrel.
