Narrative:

While moving an OTS aircraft off the gate to the hangar and assigned to bring a replacement MD80; approaching the gate; left wingtip struck a service truck which from my view looked clear. I centered the aircraft on centerline and then felt the tractor shake. I then looked back at the nosewheels to see if the towbar disconnected and again at the wingtip and saw a man waving his hands. I immediately used the hand brake and foot brake to stop the aircraft; but it was too late. Although it has been standard practice to use only one wing walker here at ZZZ; in the future I will ensure I will only move an aircraft if I have two wing walkers. Supplemental information from acn 792797: we were bringing a replacement MD80 aircraft back to the gate. As we came to the gate area; the tractor driver stopped and I got off the tractor and wing walking on the right side. Before we got all the way on the gate; the tractor driver stopped and I realized something was wrong. When I looked at the left side of the wing; the aircraft had struck a service truck. To prevent this; always use two wing walkers. The current procedure is to use only one wing walker.
