Well, there has been a positive development. I just received notification from PTL that the the part has been shipped via FedEx and giving me a tracking number. Checking with FedEx, the package has been picked up and is on the way. It is scheduled for delivery on Friday, July 10.
So, it appears that someone at PTL actually did expedite the shipment. That sure beats "that's not gonna happen!" My suspicion is that the guy who took the original order was responsible for expediting it. THANK YOU!
While it was shipped FedEx Ground rather than 2nd Day as requested, three days is OK. The part was billed out at $85.09 as shown on their parts page and shipping was billed at $23 for a total of $108.09. That's still less than half of what Newmar was asking. Now, in fairness, the Newmar price does include shipping at no additional charge.
