If you can get a decent warranty, and 30 days is not enough, then the dealer might be worth the money. Problem with a 30 day warranty is you probably won't camp but once or twice in that 30 days. It may not rain in that time. You may not use both the air and the furnace in that time. And the lipstick they put on the pig won't be worn off by the end of the 30 days. If you buy used and the dealer won't help you out, don't even bother calling the factory. If you buy new and the dealer won't help you out the factory is your back-up.
