Narrative:

Upon taxiing in to gate in detroit, we noticed equipment including a large truck close to our parking space. Because we had both a marshaller and a wing walker on the truck side, we elected to continue. We were still receiving a taxi forward sign from the marshaller and a thumbs up sign from the wing walker when the right wing impacted the truck. Neither noticed that we had collided with the truck. The wing walker was approximately 20 ft from the wing and never looked at it. Contributing factors were snow obscuring safety containment lines, and the marshaller and wing walker not looking at the airplane.
