My Wife and I purchased a Keystone Cougar TT this spring from Tacoma RV in Fife and have been very happy with both the trailer and the dealership. Zero issues so far, even after a 3,000 mile road trip to Arches NP & the Grand Canyon. We looked at over 18 brands of trailers and visited 12 dealerships to narrow down the options. Seriously considered Lance and Arctic Fox, but ended up with the Cougar as a good balance of weight, price, features, and tank capacities.
Now is a great time to buy a 2015 "leftover". Check out the reputation of dealerships and their service departments on Yelp or Google reviews. Be prepared for a lot of "smoke and mirrors" with the pricing. Found the identical unit we liked at two different dealerships. With a bit of grinding, it turned out that there was less than $200.00 difference with the "out the door" prices at each dealership. Good luck with your search and purchase!
