Abstract
A bearing guide for a hitch allows lateral movement of the hitch. The bearing guide is elevated relative to the bearing surface. Two trucks roll on wheels each about their own elevated guide for fore-and-aft rolling of the hitch point. The bearing guide also provides a keyway which receives a locking key. The locking key is supported on both sides of the keyway by a plunger control rod, and can be unlocked by pulling and rotating a handle. When the towing vehicle is driven to relocate the hitch point, the locking key reengages itself into a different keyway on the bearing guide.
