I don't think Tiffin builds any better than Fleetwood, but their customer service is really excellent. Especially is you take the coach to the Tiffin factory in Red Bay, AL. But Fleetwood factory service (Decatur, IN) is also excellent. Dealer service typically depends more on the dealer than the brand, but Tiffin is probably a bit more flexible than Fleetwood if you have serious problems.
