Keystone RV Carbon Toy Hauler Fifth Wheel RVs For Sale
The Keystone Carbon toy hauler has been built for whatever road you have ahead of you! Whether you find yourself traveling down dirt roads or along the highway, you can travel confidently with the lighter, more-affordable Carbon toy hauler. Even the most seasoned of adventurers will be impressed by the Carbon and all that it has to offer. Some of those impressive features are the Thomas Payne® furniture with heat/massage, 50" LED TV, the Extreme Temperature package, and Dyna Span® one-piece floor decking in the garage area.
The Roto-Flex pin box will absorb road shock so that you can have a smoother ride with less wear and tear on your vehicle, and the frame-welded tie-downs have an industry-leading capacity at 5,000 LBS so that you can haul safely and securely. The Carbon floorplans have been designed for entertaining, and the interior features, like the soft-close cabinet doors, solid-surface countertops, and farmhouse stainless steel kitchen sink, are going to make it easy to host family and friends. Some of the other advantages that come with the Carbon are the Dexter E-Z Lube 7,000-LB axles on fifth wheels and 6,000-LB axles on travel trailers, the exclusive Omni-Chill A/C, and the automotive-grade painted fiberglass front cap that includes Keystone's exclusive Key Shield™ protective coating.

Manu-Facts:

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.
