Billy at Northgate is a nice guy I have bought 2 from them and they were way off on trading difference on the Landmark. We did look at the 2 that they have on there lots. Ours should be in anyway now. We camp in Pigeon Forge since it is only about 30 miles away a lot throughout the summer, Myrtle Beach and Disney World.
The 2013s have a better warranty, remote control system, and not for sure what else. We got the Chocolate Full Body Paint with the French Roast Inside with lots of options less Exterior Entertainment and a few other items.
