Our nearest RV Dealer is in town, but they don't have more than a RV or two on the lot. Our next nearest dealer is almost an hour away, so for us there is no local dealer. We like Jayco and the nearest Jayco dealer (last I checked anyway) was 2.5 hours away. We ended up buying our previous MH from a dealer in NJ. Had to take it in for warranty work twice. We didn't use the nearest Jayco dealer because they were one of those, "didn't buy it from us, we'll get to it eventually" types. We took it to the next nearest Jayco dealer that was 3.5 hours away. They were happy to do the warranty work and had it done in about a week, both times.
If where you want to buy it from has local attractions, make a trip out of it. For instance, we took our MH to a dealer in North Charleston, SC, 3.5 hours away for warranty work, we dropped the MH off at the dealership, spent the day in Charleston and then went home. When it was time to pick it up, we did the same thing, spent the day in Charleston and then picked the MH up on the way home.
As Bmach said, keep the money in your pocket. Unless a major appliance fails or you have construction issues, most warranty work is stuff you can do yourself if you are handy. You the money you saved to make the fixes.
