It's important to note RV dealers are not franchises the way new car dealers are. This is an important distinction because car dealers are required honor warranty regardless of selling dealer, RV dealerships aren't required too. That said many do, might not give the same priority to those who didn't purchase from them.
I might call you local dealers service department, pretend you have an in warranty unit bought else where and see what they say. Maybe the simple won't do the work, or will require you to pay our of pocket and deal with reimbursement directly on your own.
None of this would prevent me from traveling two hours. The warranty is only 2 years, and with 2 JayFlights as my experience I have had very few problems.
