I was unaware that the warranty co's require that practice. Doesn't make sense to me to let his coach sit for months waiting for a part that probably can be replaced with another that is available. It just figures that Monaco would use a part or piece of equipment that is special order and costs a small ransom.
I talked to Jerry a couple times on the phone. He is stuck in a bad spot. He seems to be in the "perfect storm" for motorhomes.
First, the extended warranty company has it's requirements. But, second, the company doing the work has some too. The pump failure sent metal down stream and attacked the fan motor and power steering motor. All three have to be replaced.
Second, the service facility has requirements too. If a "used" or "surplus" part is installed, and there is a failure in the system after the repair, would you expect the service shop to back up their work?
On top of all that, this failure is so rare, that should someone put the pump in stock in their parts room, it could be old and out of warranty before it ever left the parts room.
Making everything worse, the company that made the pump for Monaco apparently went out of business in the Great Recession by selling out to an Italian company with worldwide applications. It can be entertaining and frustrating to Google for "SAI Hydraulics".
Jerry's and Chris's only choice seems to be renting from CruiseAmerica if the want to get out of Seattle's gloomy winter weather!
