Learn more about how Climate Guard provides year-round insulation as well as protection in cold winter and hot summer months.

BETTER CONSTRUCTION AND INSULATION FOR HOT & COLD

• Insulated gooseneck, bulkhead divider and sealed pin box (5th Wheels). Cougar fifth wheels feature a fiberglass insulated gooseneck, bulkhead divider wall, and a foam gasket sealed pin box to protect the upper deck from the elements.

EXTRA SECURITY WHEN TEMPERATURES DIP

• Heated pass-through storage (fifth wheels). A heat register is positioned behind the convenience center in the pass-through storage to prevent water lines from freezing.
• 12V electric heat pads on all holding tanks. Helps prevent holding tanks from freezing while camping and can also be used in transit.
• 30K BTU Furnace
• Heated and enclosed underbelly. Cougar's sealed Coroplast underbelly has a layer of astro-foil insulation beneath the holding tanks with a second layer of fiberglass insulation above the tanks. A heating duct runs adjacent to the water lines pumping heat around the fresh tank to prevent tanks, waterlines, and gate valves from freezing.
• Heated and enclosed convenience center.
• PEX plumbing. Resistant to corrosion, pitting, and scaling, this residential plumbing uses fewer fittings, thereby reducing potential leaks. When compared to conventional copper and CPVC lines, PEX aids with heat retention in hot water lines, and diminishes condensation in cold water lines. Perhaps most importantly, PEX plumbing has the ability to expand up to three times its diameter should water lines freeze.

WARM WEATHER COMFORT

• 18K Furrion High Efficiency Chill Cube A/C
• 15K Ducted Bedroom A/C
• 3rd A/C Prep
• Radiant foil barrier in front cap. Radiant foil reduces amount of radiant heat that can come from the units front cap during summer months.

Cougar Max Turn

Combining focused design and unique product specifications, Max Turn Technology is the leader in optimum turn radius.

MaxTurn™ Technology

MAX TURN™ MAKES TURNING AND MANEUVERING A BREEZE

Keystone fifth wheel RV owners can make tight turns more confidently with Keystone's EXCLUSIVE MaxTurn™ Technology. Developed by the Keystone Innovation Lab, MaxTurn's patented tube frame design combined with a tapered fiberglass front cap provides and additional 8" of turning radius than the standard straight tube design. MaxTurn delivers an expected turning radius of more than 95° without an expensive and difficult to maintain swivel hitch pin.

Key features include:

• Single-piece bent tube replaces a welded three-piece frame
• Eliminates need for swivel hitch pin and the maintenance that comes with it
• 8" more turning radius, more than 95°
• Greater manueverability and safety
• Protects tow vehicle from damage

Innovation Leadership

These models feature exclusive ground-breaking components and technologies from the Keystone Inovation Lab.

HYPERDECK™ RV FLOOR

HIGH-PERFORMANCE, WATER RESISTANT RV FLOOR

Stronger, lighter and more resilient than traditional wood laminated flooring, Keystone's exclusive HyperDeck™ is an excellent example of how the Keystone Innovation Lab challenges industry norms to build better RV's. By its nature, traditional wood floor construction presents the possibility of taking on water, a watchout for RV owners who need to remain vigilant to keep moisture out of their coaches. Hyperdeck replaces wood with 100% inorganic materials, designed to resist water and water damage. That's peace of mind that's worth its weight in gold.

SIX WAYS HYPERDECK RV FLOORS OUTPERFORM TRADITIONAL LAMINATED PLYWOOD CONSTRUCTION

1. 100% inorganic and water resistant
2. Fiberglass-reinforced polypropylene layers increase strength and resist soft spots
3. Reduces flooring weight by up to 25% for easier towing
4. Less likely to degrade over time
5. Increased screw retention keeps RV build secure
6. High density foam and polypropylene construction increases insulation and dampens noise
