My boss up here at the office has an OEM Nissan Pathfinder (99.5-04)/ QX4 (99-04) tow hitch for sale. It includes:

Hitch, receiver, 2" ball, harness, instructions.

Hitch is only 3 months old, and consequently in very good condition- does not need as his new P/F already has one.

Asking only $135. Anyone interested, please contact me, and I will relay your contact info to him.
