It must be a regional thing. We don't have that problem. My truck bad water pump fixed in two day. We had another truck towed back for a the same problem fixed in 2 days. Dolly broken leaf spring fix in 2 days. I and other drivers have brought back parts from XMI shop for our trucks and trailer. I known of drivers including me bring back brakes and drums, leaf springs, water pumps, air bags even a turbo. The longest anything has sat O/S at my barn were trailers that had roof damage and one truck with a trans problem that was tow to the dealer within 4 days and we had it back in 2.
