Measuring approximately 32 feet 8 inches long, the Cougar 28RLI offers an open living area with comfortable seating, residential-style kitchen amenities, and storage throughout the trailer. Part of Keystone RV's established Cougar lineup, this fifth wheel also incorporates modern construction materials, towing technology, and climate-protection features designed for regular recreational use. For customers looking for a Keystone Cougar fifth wheel in Kitchener, Ontario, the 28RLI provides a practical combination of living space, comfort, and campground convenience.

Spacious Rear Living Room With Opposing Slide-Outs

One of the main features of the 2026 Cougar Half-Ton 28RLI is its open rear living room design.

The opposing slide-outs create additional floor space in the centre of the trailer, providing room to move between the kitchen, dining area, and rear seating. This arrangement makes the 28RLI particularly appealing to couples who spend extended periods camping or want a comfortable interior for entertaining guests.

The rear living area includes a tri-fold sleeper sofa, theatre seating, and an entertainment centre with a television and electric fireplace.

Large windows bring natural light into the interior and provide views of the surrounding campsite. The rear sofa also provides additional sleeping accommodations when needed.

The open floorplan creates a distinct living area without separating it from the kitchen and dining space.

Residential-Style Kitchen With Centre Island

The kitchen is another defining feature of the 2026 Keystone Cougar 28RLI.

The centrally located kitchen island provides additional countertop space for preparing meals, serving food, and cleaning up. Its position within the opposing slide-out arrangement helps maintain an open flow through the main living area.

Kitchen equipment includes a 12V refrigerator, three-burner cooking range, oven, microwave, and an undermount sink with a high-rise faucet.

The 12V refrigerator provides food and beverage storage for camping trips, while the cooking appliances allow meals to be prepared inside the fifth wheel.

Residential-style cabinetry, drawers, and pantry storage provide space for dishes, cookware, dry goods, and other kitchen essentials.

The kitchen island also helps separate the food preparation area from the seating and entertainment space without closing off the room.

Comfortable Dining Area

The Cougar Half-Ton 28RLI includes a dedicated dining area positioned within the main living space.

The dining arrangement provides a place for meals, morning coffee, or other activities while camping.

Its location near the kitchen island makes serving and clearing meals convenient.

The open design also allows the dining area to remain connected to the rear living room, creating a practical arrangement for couples and visiting guests.

Private Front Bedroom With King Bed

The 2026 Cougar Half-Ton 28RLI features a private front bedroom with a king bed.

The separate bedroom provides privacy from the main living area and offers a dedicated sleeping space for longer trips.

Storage includes wardrobe space, drawers, and underbed storage for clothing, bedding, and personal belongings.

The bedroom also incorporates electrical outlets and charging connections for everyday convenience.

The private bedroom arrangement is useful for customers who want a distinct sleeping area rather than a convertible bed located within the main living room.

Bathroom With Large Shower

The bathroom is located between the front bedroom and main living area.

It includes a shower with glass door, skylight, porcelain toilet, vanity, sink, and storage for toiletries and towels.

The shower provides a dedicated bathing area, while the skylight helps bring natural light into the bathroom.

The vanity and storage compartments provide space for everyday personal items.

The bathroom's location allows convenient access from both the bedroom and living area.

Keystone HyperCore Composite Construction

The Cougar Half-Ton lineup incorporates Keystone's HyperCore composite sidewall technology.

HyperCore uses composite materials within the exterior wall assembly and provides an alternative to traditional wood-based construction.

The high-gloss exterior finish contributes to the fifth wheel's appearance while the composite wall system forms part of Keystone's modern construction approach.

For customers comparing fifth wheel construction methods, HyperCore is one of the technologies Keystone highlights throughout the Cougar lineup.

HyperDeck Composite Flooring

The 2026 Cougar Half-Ton 28RLI incorporates Keystone's HyperDeck composite flooring.

HyperDeck is designed as a water-resistant alternative to traditional wood-laminated RV flooring.

The composite construction is intended to provide strength and durability while reducing reliance on wood-based materials.

This technology is part of Keystone's broader approach to RV construction and long-term serviceability.

MaxTurn Fifth Wheel Towing Technology

Keystone's MaxTurn technology is designed to improve turning clearance between the fifth wheel and pickup truck.

The system incorporates changes to the frame and front cap design to help provide additional manoeuvring room.

This can be useful when navigating campground roads, making tighter turns, and positioning the fifth wheel at a campsite.

Actual turning clearance depends on the truck, bed length, fifth wheel hitch, and trailer configuration.

Road Armor Suspension and Towing Features

The Cougar Half-Ton 28RLI includes towing and suspension technologies designed to help manage road movement.

Keystone's Road Armor suspension system uses shock-absorbing equalizers to help reduce the transfer of road shock through the trailer.

The fifth wheel also incorporates a Helux coil spring pin box, which is designed to help absorb movement between the truck and trailer.

Additional towing equipment includes Goodyear Endurance trailer tires, anti-lock trailer brakes, and a full-size spare tire.

These components are part of Keystone's approach to fifth wheel towing performance and durability.

Electric Automatic Levelling

The 2026 Keystone Cougar 28RLI includes an electric four-point automatic levelling system.

This feature simplifies campsite setup by helping level the trailer after it has been positioned.

Automatic levelling can be particularly convenient for owners who frequently travel between campgrounds.

It reduces the need for repeated manual adjustments when setting up the fifth wheel.

Climate Guard Protection

Keystone's Climate Guard protection package includes equipment designed to help maintain interior comfort and provide additional protection for plumbing components.

The Cougar Half-Ton 28RLI features a heated and enclosed underbelly, insulation in key structural areas, and heating equipment intended to support extended-season camping.

The enclosed underbelly helps protect plumbing and holding tanks from exposure to outside conditions.

Additional insulation is incorporated into areas such as the front cap and slide-out floors.

These features are useful for customers who camp during spring, fall, or periods of changing weather.

Appropriate winterization and cold-weather precautions remain necessary when temperatures fall below freezing.

Air Conditioning, Furnace and Tankless Water Heater

The 2026 Cougar Half-Ton 28RLI includes an 18,000 BTU Furrion Chill Cube air conditioning system and a 30,000 BTU furnace.

The air conditioning system provides cooling during warmer weather, while the furnace supplies heat during cooler camping conditions.

A tankless on-demand water heater provides hot water for showering, washing dishes, and everyday use.

The combination of heating, cooling, and hot water equipment makes the 28RLI suitable for a range of camping conditions.

Keystone Electrical and Technology Features

The Cougar Half-Ton lineup incorporates several Keystone electrical technologies.

Giggy Box Electrical System

Keystone's Giggy Box organizes important 12V electrical connections within a protective enclosure.

The system is designed to make circuits easier to identify and access during servicing.

Colour-Coded Wiring

Keystone's colour-coded wiring system helps technicians identify and trace electrical circuits.

This can simplify maintenance and troubleshooting.

KeyTV Television System

The KeyTV system organizes compatible antenna, cable, and satellite television connections.

It provides a centralized approach to television signal distribution throughout the fifth wheel.

SolarFlex Solar Power

Keystone offers SolarFlex solar power configurations for Cougar Half-Ton fifth wheels.

Depending on the installed package, SolarFlex can provide solar charging and expanded electrical capabilities.

The specific solar panels, batteries, charge controller, and inverter equipment should be confirmed on the individual trailer.

Exterior Features and Campground Convenience

The 2026 Cougar Half-Ton 28RLI includes exterior features designed for regular campground use.

Two electric power awnings provide shaded outdoor space, while exterior lighting helps illuminate the campsite during evening use.

The fifth wheel also includes pass-through storage for camping chairs, hoses, tools, and other outdoor equipment.

Additional exterior features include utility connections, a campsite convenience centre, exterior speakers, and preparation for a rear observation camera.

The exterior storage and utility arrangements help simplify campsite setup and keep frequently used equipment organized.

Towing Considerations for the Cougar Half-Ton 28RLI

Although the Cougar Half-Ton name suggests compatibility with certain half-ton pickup trucks, the 28RLI is not suitable for every half-ton truck.

With a published shipping weight of approximately 9,050 lbs, the trailer's actual loaded weight will increase when personal belongings, camping equipment, water, and other cargo are added.

Fifth wheel towing also places significant weight directly over the truck's rear axle.

Customers should review the trailer's gross vehicle weight rating, loaded pin weight, truck payload capacity, rear axle rating, and fifth wheel hitch rating before selecting a towing combination.

Depending on the tow vehicle's specifications, a properly equipped three-quarter-ton truck may be a more suitable choice.
