I just purchased a 2018 3560 SS Big Country, this wasn't originally planed. I Bought a new to me 2015 keystone Cougar from the same dealer last Wednesday, went camping the same day and it rained for two days. The camper had a very bad leak and the dealer agreed to give me back my money for another purchase. This is the first brand new camper I have ever bought and I hope fingers crossed it's problem free.
