2026 Keystone Cougar Half-Ton East 22MLS

2026 Keystone Cougar Half-Ton 22MLS – Towable Luxury Meets Adventure-Ready Versatility

If you’re looking for the perfect blend of rugged capability and refined comfort in a compact, easy-to-tow travel trailer, the 2026 Keystone Cougar Half-Ton 22MLS delivers on every front. Purpose-built for couples and small families who crave adventure without compromising on modern amenities, this sleek, efficient, and intelligently designed RV sets a new benchmark for premium travel in a nimble footprint.

From its aerodynamic profile to its plush interior finishes, the 22MLS represents the Cougar legacy of innovation, quality, and luxury—all in a compact, lightweight package under 27 feet in length. It’s perfect for weekend getaways, national park road trips, or full-time living for minimalist adventurers.

The first thing you’ll notice about the Cougar 22MLS is its striking presence. The bold front cap features Cougar’s signature high-gloss fiberglass with aerodynamic contouring for improved towability and fuel efficiency. The exterior sidewalls are laminated and framed with durable aluminum, helping reduce weight without sacrificing structural integrity.

This 2026 model is equipped with Keystone’s HyperDeck™ flooring system, which resists water damage, rot, and delamination, making it perfect for those who want to camp off the beaten path. Coupled with the Climate Guard™ all-season insulation package, the 22MLS is engineered to handle extreme temperatures, so you can confidently travel year-round—whether you’re chasing sunshine or cozying up during winter.

You’ll also appreciate thoughtful outdoor conveniences, like the power tongue jack, electric stabilizer jacks, and pass-through storage with magnetic slam-latch doors. The large power awning features LED strip lighting, creating the ideal atmosphere for lounging or entertaining at your campsite. The exterior also includes a spray port, backup camera prep, roof ladder, and Goodyear Endurance tires mounted on aluminum wheels.

Measuring approximately 26’10” in overall length and weighing around 5,500 lbs dry, the Cougar 22MLS packs maximum functionality into a single-slide layout. It’s ideal for half-ton tow vehicles and features a rear kitchen, a large slide-out, and a private bedroom up front—all designed to make your time on the road as enjoyable and stress-free as possible.

The open-concept living area feels far more spacious than its size suggests, thanks to 7-foot ceilings, panoramic windows, and smart design elements that increase livability. Every square inch has been optimized to provide a feeling of luxury and space in a compact, nimble format.

The fully equipped rear kitchen is a standout feature of the 22MLS, offering residential-style functionality in a compact footprint. It includes:

• A 12V GE residential refrigerator (10 cu. ft.)—large enough for extended stays

• A three-burner Furrion® gas cooktop with oven

• Microwave with vented range hood

• Seamless pressed countertops with LED-lit backsplash

• Deep stainless-steel sink with high-rise faucet and pull-down sprayer

• Abundant overhead cabinetry and under-sink storage

Whether you’re meal prepping before a day of hiking or making breakfast for two on a lazy Sunday morning, this kitchen gives you the space, storage, and style to cook in comfort.

The Cougar 22MLS features a large slide-out that houses your choice of theater seating, a tri-fold sleeper sofa, or an optional dinette, depending on configuration. Most popular is the dual recliner theater seating with heat and massage—positioned directly across from a 40" LED HDTV on a swivel mount, complete with a built-in Furrion entertainment center and Bluetooth-capable sound system.

Large panoramic windows on both sides of the living area fill the space with natural light during the day and provide expansive views of the outdoors—whether you’re parked in the forest or overlooking a lake.

Under the seating, you’ll find additional storage—ideal for blankets, games, or travel gear. The Cougar is also prepped for Wi-Fi, solar power, and satellite, ensuring you stay connected even when you’re off the grid.

The private front bedroom of the 22MLS features a true residential 60" x 80" queen bed, not the shorter RV variety, which means you’ll sleep soundly every night. Dual wardrobes on either side of the bed offer hanging space, while overhead cabinets and nightstands provide plenty of room for books, electronics, or clothing.

There’s also storage under the bed, complete with gas struts for easy lifting. USB charging ports and 110V outlets on both sides of the bed make it easy to keep your devices charged. A sliding door separates the bedroom from the living space, giving you added privacy when you need it.

If you're traveling with guests or a child, the tri-fold sofa or dinette option in the living room easily converts into extra sleeping space, making this a highly versatile rig.

The Cougar 22MLS bathroom doesn’t feel like an afterthought. Keystone has designed a large corner bathroom with a residential-style radius shower and glass doors. Inside, you’ll find:

• Skylight over the shower for natural light and extra headroom

• Porcelain foot-flush toilet

• Medicine cabinet with mirror

• Large countertop with plenty of space for toiletries

• Deep sink and high faucet

• Generous linen cabinet storage

Hot water is supplied by a quick-recovery 6-gallon gas/electric DSI water heater, ensuring warm showers even when boondocking.

With Cougar’s Climate Guard protection package, including 12V tank heaters, foil-wrapped insulation, and a 35,000 BTU furnace, you can comfortably camp in all seasons. The 15,000 BTU ducted A/C system keeps the coach cool during summer, while fully insulated walls and floors retain warmth in the winter.

The 2026 model comes pre-wired for 200W solar, with the optional SolarFlex™ 400i package for those who want more off-grid capability. This package includes:

• 2x 200W solar panels (expandable)

• 30A MPPT solar charge controller

• 2000W inverter prep

All Cougar models now include TPMS prep, Dragonfly lithium battery compatibility, and smart monitoring via the Keystone Compass Connect app, allowing you to control lighting, slide-outs, and tank levels from your phone.

As with all Keystone Cougars, the 22MLS is built with Keystone's exclusive Norco BAL HyperDeck™ composite floor, which eliminates wood substrate and reduces weight while improving water resistance. The sidewalls are made with aluminum framing and Azdel composite panels, which won’t rot, mold, or delaminate.

The one-piece TPO roof is walkable and comes with a 12-year warranty. Underneath, you’ll find a fully enclosed and heated underbelly, protecting plumbing and tanks during cold-weather travel.

Cougar’s industry-leading warranty backs the build quality:

• 3-year limited structural warranty

• 1-year limited base warranty

• Extended coverage available through participating dealers

What sets the Cougar 22MLS apart from other single-slide travel trailers in its class is the seamless integration of livability, tech, and long-term durability. It’s not just a travel trailer—it’s a mobile suite that invites you to go further, stay longer, and camp smarter.

Highlights at a glance:

• Half-ton towable and under 27 ft

• Rear gourmet kitchen with large fridge and oven

• Theater seating or dinette option in slide-out

• Private front queen bedroom with full storage

• All-season Climate Guard™ protection
