We purchased a 2014 Keystone Terrain 321TBH in June of last year and we absolutely LOVE this TT. I tow it with a half ton, 2011 Silverado Crew Cab Z71 with the tow package and the engine and tranny cooler and do quite well with it. This one does not have the outside door for the bathroom but does have the full outdoor kitchen which is my favorite part. Its very spacious inside. This model can sleep up to ten but there are only five of us. A couple of things I did right out the gate was install a power tongue jack (trust me its worth the money) and ordered a new deluxe mattress for the master bedroom. I also installed another TV in the master bedroom and will be putting one in the kids bunkhouse. You can't go wrong with the Terrain.
