We bought ours from RV Wholesalers in 2006. Couldn't be happier. Saved over $6K from local dealers.
The local dealers had ZERO trailers in stock like we wanted. They would have to order one, just as we did, then charge me $6K for the effort??? Uh, no.
As for the FACTORY warranty, don't believe a local dealer if they tell you (as they did us) that they would service trailers they sold, and not others. I walked directly over to the service department after being told that by a salesman. The service manager said that's a bunch of $%@&, and they'd gladly do ANY work on ANY trailer, especially factory authorized work!
When there was recall work on our fridge, the local dealership that doesn't even sell Rockwoods, did the work, no questions asked.
I do try to buy locally, but giving them an extra $6K is ridiculous.
