My 2 cents. I bought a 2 year old Keystone Springdale in 2013. It's a 311RE and was owned by one of the mechanics at the dealership. He traded it on a new 5th wheel. It was taken care of to the best standards. I bought it for about $10,000 below the cost of a new unit. The best thing about it was that all the bugs had been worked out in the first 2 years and I've had 0 problems since purchase. I'm planning on trading it in on a new one in 2020 and getting the same model as it fits what I need perfectly. All in all a quality unit.
