I towed a 2010 Keystone 250RS with a 2010 Armada. I loved, loved, loved the armada. It was a great tow vehicle for a 1/2 ton SUV. That said, my trailer topped at 7500lbs and I really had to be careful to travel light, ensure my extra weights (rubbermaid of wood, grills etc) were over the axles of the trailer, and that all the tires had the right level of air in them. I hauled tons with it, from PA to Tennessee and PA to Kentucky. I've also done the central PA mountains with it, and it did great (yes, it yells on the hills, but it doesn't lack power). I wouldn't have done any heavier of a camper with it though. The camper you're looking is almost the weight of mine loaded...I don't know that I'd go that heavy. It's a great truck, but a 1/2 ton is a 1/2 ton. The other issue with it is that it's not very forgiving of any driving mistakes - it won't compensate for a 'slam on the brakes' stop...you better manually engage the brake controller in those cases. It will sway like crazy if the weight distribution isn't 100% dead on (highly recommend the reese dual cam...loved it), you'll know it's back there if it's windy if the WD is even slightly off.
It is a great truck for hauling, I personally just feel you might be just slightly over a comfortable weight to tow with it. A slightly smaller camper, and I'd recommend it 100 times.
