RV parts shortages

Many dealerships just don't look outside their normal channels. I was Emergency Purchasing Agent for a large mid-west heavy duty truck group that traded on exceptional customer service. My job was to expedite hard to get service parts. Our service manager would occasionally pop into my office to tell me one of his good customers was stranded in another state at a dealership that told the customer his needed part wasn't available. Usually, I could find it someplace and still get it shipped out of the warehouse next-day-air, often from the west coast. My service guy loved to phone the service manager where our customer was stranded and tell him the part he couldn't get was being drop-shipped to him and would be there the next morning.
