The dual entry bath includes a shower with a seat for added comfort, and the front master bedroom will feel just like home with its king bed slide out and master closet. There is also a dresser and stackable washer and dryer prep if you want to add those appliances!

There are many more Keystone exclusives, like the Tru-Fit slide construction, the in-floor heating ducts, KeyTV™, and much more to bring you a full-packed, luxury fifth wheel!
Anne was an excellent salesperson. She took her time to show us and help us over several months. Always gracious and considerate until we made a decision. We got a fair trade and a great deal.
Much in contrast to an unnamed out of town place where we were under intense pressure to buy the moment we stepped inside.
The rest of the staff were equally helpful. Financing was easy and straightforward. - Joe
