Keystone Cougar Half-Ton Fifth wheels - Your next fifth wheel trailer!

The Cougar Half-Ton fifth wheel lineup delivers a blend of smart engineering, modern comforts, and dependable versatility — built to give you the flexibility of a towable fifth wheel without unnecessary bulk. At Mobilife RV we appreciate how these units strike a balance between strength, livability, and tow-vehicle friendliness. If you’re looking for a fifth wheel that’s manageable, well-constructed, and ready for real-world use — whether seasonal camping or extended trips — the Cougar Half-Ton family stands out as a strong choice.

Features and Options

The 2026 Cougar Half-Ton fifth wheel lineup is built on an individually engineered structural I beam chassis with stamped steel cross members and outriggers, giving each model a stable, dependable towing foundation. The units ride on heavy duty axles, properly rated to each floorplan, supported by ABS braking systems and paired with Goodyear Endurance E-rated tires and a full-size spare, creating a combination designed for long lasting performance on the road. Many models also include advanced suspension support such as the Road Armor Pin Box, which absorbs road shock for smoother towing, as well as an optional electric four point auto leveling system that makes campsite setup faster and easier for both short and extended stays. The exterior walls use HyperCore composite construction finished in high gloss Fibrogloss, keeping weight low without sacrificing durability or weather resilience. The floors are built using HyperDeck Flooring, an inorganic and water resistant composite, offering long term protection from rot, soft spots, and moisture damage.

The underbelly is protected by a one piece polypropylene enclosure and the holding tanks include 12-volt heat pads with secure steel supports and Tank Guardian Straps, helping provide more camping season flexibility, especially in colder Canadian climates. Overhead, each trailer is protected by the AlphaPLY Roof Membrane backed by a limited lifetime warranty and paired with tinted dual pane frameless safety glass windows, improving insulation, climate comfort, and exterior noise reduction. Storage is oversized, travel ready, and secured behind composite slam latch compartment doors making it easier to pack more gear without concern for added strain. A 2-inch rear accessory receiver hitch expands the trailer's carrying options for cargo trays, adventure add ons, or bike carriers.

Campsite convenience is built into the Cougar Half Ton design, including an exterior spray port with both hot and cold water, an LP quick connect fitting for grills or accessories, and a 55-gallon fresh water system supported by steel reinforced tank holding infrastructure. Electric awnings equipped with LED lighting and optional slide toppers extend outdoor living space while also helping protect key expandable areas from seasonal debris or weather. The interiors open up with slide out living rooms supported by Tru-Fit slide construction, creating a space that feels purposeful, roomy, and comfortable. The cabinetry uses shaker style hardwood doors and drawers finished with interior molding details that bring a residential feel into every trip.

The kitchen layout includes seamless pressed countertops, an under mount stainless or black stainless sink with high rise faucet and sprayer, a 12-volt refrigerator, built in microwave, and cooking appliances that make full meal service easy whether parked or traveling. Bathroom layouts include seamless countertops, recessed medicine cabinets, skylight equipped showers where applicable, and smart linen storage. Sleeping areas in many floorplans include queen or optional king beds with under bed storage and travel ready USB or 12-volt charging access points. The climate systems include ducted air conditioning support in bedroom and living zones supported by Tuf-Lok duct joiners, a powerful central furnace, and optional in floor heating ducts depending on model and build.

Electrical access is organized through the GIGGY BOX unified, color coded 12-volt wiring harness system with battery disconnect, supporting safer maintenance and better long term troubleshooting access. Connectivity is supported by the omni directional 360° rooftop antenna with satellite pass-through and the KeyTV System Controller, allowing campers to manage multi-source entertainment feeds while parked or traveling. Each Cougar Half Ton unit is backed by a 3-year limited structural warranty with 1-year base coverage and includes owner support documentation and service tracking through the Keystone RV Owner's App, providing simplified warranty management and product support access for buyers exploring models at Mobilife RV.

What This Means for You

Choosing a Cougar Half-Ton fifth wheel from Mobilife RV means getting an RV built from the ground up with thoughtful engineering and real-world practicality. The structural chassis, suspension upgrades, and reinforced axles provide confidence when towing, while composite wall and floor construction — with waterproof, inorganic materials — means you don’t have to worry about wood rot or structural damage over time. These build details add long-term value especially if you travel often or store your unit outside during off-season months.

Inside, the Cougar Half-Ton’s combination of residential-style finishes, spacious floorplans, and modern utilities delivers a living experience closer to a home than a typical trailer. Whether you’re cooking meals, relaxing in the living area, or sleeping comfortably after a long day of driving or hiking, the trailer’s layout and finishes support comfort and convenience. The kitchen and bathroom amenities go beyond basic camping — they make extended stays feasible and enjoyable.

Weather protection, climate control systems, and insulated holding tanks give flexibility to camp in different seasons and climates. Whether you’re heading north for late-season foliage, planning a spring trip, or escaping to a warm destination, the improved insulation and utility systems help keep you comfortable.

The exterior features and storage solutions make the Cougar Half-Ton versatile. With generous storage capacities, utility ports, plumbing and electrical systems designed for real use, and exterior fittings ready for accessories or cargo carriers, it adapts to a wide range of travel styles — from weekend getaways to multi-week adventures.
