- Dual Entry
- Three Slides
- Electric Bed
- Bath and a Half
- Stainless Steel Refrigerator
Take one look at this toy hauler and you can be sure you've just found your new RV. After setting up camp and going for a quick ride on your dirk bikes, stretch out on the L-shaped sofa that includes a recliner on the end. The 50" LED HDTV is directly across from the sofa for convenience and the counter peninsula behind the sofa allows the chef of the family a view of the TV as they cook. Your guest will appreciate the 13' separate garage that includes an electric bed with dual opposing sofas, its own exterior entry door, and a convenient half bath! This model also includes a front master suite with a queen bed, dual nightstands, a slide out wardrobe, and access to the double entry bath; now that's what I call luxury!
With any Carbon toy hauler travel trailer or fifth wheel by Keystone you will appreciate the heated, enclosed underbelly that allows you to camp in any weather, the 30 gallon generator fuel tank with a fuel station to keep your toys ready to ride, and double welded aluminum construction for a strong, durable unit. Each model includes residential reclining furniture with heat, light, and massage, stainless steel appliances, USB outlets in the sofa slide outs, and solid surface kitchen countertops for all-around luxury. The Dyna Span floor decking provides strength and stability for any toys you may bring along, and these travel trailers and fifth wheels feature plenty of storage space, including a heated and lighted pass-through storage for all your riding gear!
The fast, efficient, courteous service I have received when dealing with your service centre. I am a new owner and need to learn a lot. Your staff are exceptionally helpful and kind.
I keep recommending your company for everything and I would not if I had not received such good service.

At Keystone we do things differently, and have since we first opened our doors in 1996. This different way means focusing on you, our customer, and building RVs that are much more than great floor plans and prices. It starts with innovative products that are built tough, and doesn’t stop there. It’s our commitment to provide a better ownership experience. We understand that when you put your hard earned money down, you expect your RV to deliver as promised. That’s why “Building Adventures for the Long Haul” is more than just a slogan here at Keystone; it is our number one mission each and every day. It’s the reason today we are honored to say we have nearly one million Keystone owners out on the open road who we consider family.
