Just bought a used '01 GMC 2500 HD D/A and came accross this forum in my travels. Looks to be alot of good information on here. I'll sit back and pay attention until I can speak intelligently or add to the conversations.First question for any of those in the SE PA area. Anyone know of a good shop in or around the Lancaster PA area? I got a dealer warranty with the truck but want to pay someone with no vested interest to give it a good going over and give me a heads up as to any potential problem areas. Thanks in advance.
