There should not be -- but there can be. Stories abound of non-selling dealers performing work on an "in warranty" RV and requiring the customer to pay for the service in full and at shop rates then go to Jayco for reimbursement. Jayco typically doesnt pay retail rates for parts and labor so the customer very well "pays for warranty work".
I think it's wrong, shouldn't be that way, but it happens.
