I suspect some dealers delay submitting based on their volume of work.
I got lucky the Sales Manager of my area of the county put a CSR at the factory on our account that responded quickly on most every issue we had. She put us onto a La Mesa dealer that worked well with us and with the CSR. I believe we would have never gotten our issues solved without the Service writer at La Mesa and the CSR at Thor having a great working relationship. I think that the CSR when above the call of duty.
