Stay away for as long as you like with this Cougar toy hauler! Not only will you be able to bring along your large camping gear in the unobstructed pass-through storage compartment, but you will also be able to bring along your toys because of the 10' separate garage in the back. And the ramp door turns into a patio deck with magnetic screen and rear awning which makes it the perfect place to host a get-together for you and your friends.  There is a handy side man door, dual sofas, a washer/dryer prepped space, and a half bathroom adjacent to the garage.  The combined living and kitchen area offers everything you will need to be comfortable from the counter peninsula, all the appliances, and the sofa with recliners and a table, plus you will have your own full bathroom and master suite.


You won't find anything else quite like the Cougar fifth wheels and toy hauler from Keystone RV! Quality construction, stylish features, and technological innovation are just a part of what makes the Cougar a best-selling brand. You'll find an exclusive 90-degree Maxturn technology which enables you to maneuver better than ever, and the iN Command Pro Series master control panel gives you complete control over the power, slides, awnings, HVAC, and more. You will especially appreciate the heated and enclosed underbelly, which is a part of Keystone's Climate Guard protection, because it will make it possible to vacation any time of the year. And don't forget about the 81-gallon fresh water tank which will allow you to carry more fresh water so that you can stay away longer.
