In contact with Vern. He's crawling over the pallets of parts, looking for treasure. He reports many new parts, still in boxes, with part numbers. Even found a Volvo wire harness, but I don't have the part numbers for it. Anyone looking for truck parts or a project truck should be hitting the auction website.
They have a pretty good staff on their Help Desk - click on the "Contact Us" button anyswhere on the page and someone will respond quickly. Everyone on the Help Desk is a user, and an RV traveler, so they are pretty knowledgeable.
