Hey guys i found a nice 93 dually with 180,000 milies. The guy has two invoices stating some previouse work done to it. The one itself totaled $4,377.45. This invoice listed the truck had 158,000 milies on it at the time. The major thing that drew my concert was it needing a head gasket and injection pump. That just seemed odd to me with that few of miles they would go. Any reason? should i stay away from this truck? other repairs done to truck are lift pump, injectors, mechanical pump and fuel lines. Any advice would be great. thanks kyle
