At just under 31 feet long and with a 50-amp service backbone plus generous tank capacities and robust construction, the 26RES brings comfort, convenience, and versatility in a mid-size fifth wheel package. For a couple, a small family, or seasonal travelers looking for a well-rounded RV, this model delivers with a smart layout and premium amenities.
Features and Options
An engineered structural I-beam chassis with stamped steel cross-members and outriggers offers a stable, reliable foundation for towing and long-term structural integrity.
Heavy-duty axles rated 4400 lb with ABS brakes, paired with Goodyear Endurance E-rated tires and including a full-size spare, give the 26RES strong road performance and peace of mind on long hauls.
A Helux coil-spring pin box with the optional 4-point electric auto-leveling system and Road Armor shock-absorbing equalizer combine to make towing smoother and campsite setup easier.
Composite construction throughout: HyperCore composite sidewalls finished with high gloss Fiberglass and a HyperDeck 100% inorganic, water-resistant floor help reduce weight while improving resistance to moisture and rotting.
A fully enclosed one-piece underbelly and dual-heated holding tanks with 12 V heat pads, plus a sealed plumbing system, give the 26RES enhanced weather resistance and make it more suitable for cooler-season use.
Heavy-duty amenities for gear and cargo: a 2-inch rear receiver hitch for cargo or racks, oversized front storage compartment with strut-assisted baggage door, slam-latch baggage doors with composite treads, and tough-ply flooring in storage spaces provide real storage capacity and convenience.
Exterior convenience features such as a 55-gallon fresh water tank, hot and cold exterior spray port, exterior LP quick-connect, and a 50-amp Smart RV power inlet give flexibility and ease for extended trips or remote camping.
Dual awnings with LED lighting, slide-topper protection for slide-outs (optional), tinted dual-pane frameless windows (optional), a fiberglass front cap with protective coating and LED accent lighting — all enhance outdoor comfort, climate control, and exterior durability.
Inside, a tall slide-out design increases living space and headroom, with residential-style shaker cabinetry, decorative crown molding, night roller shades throughout, and dimmable ceiling lighting for a refined, home-like interior feel.
Comfortable living and sleep quarters with a standard king bed (with under-bed storage), generous wardrobe space, nightstands with outlets and USB ports, and privacy window treatments make extended stays more livable.
A fully equipped kitchen with pressed countertops, an undermount kitchen sink with high-rise faucet and sprayer, a 12-volt refrigerator, 3-burner stove with glass cover, microwave, pantry storage and well-organized cabinetry lets you cook and store food as you would at home.
Bathroom amenities that include a spacious shower with a glass door and skylight, a vanity with drawers, linen storage, a recessed medicine cabinet, porcelain toilet, quality fixtures, and a dedicated shower light ensure comfort and practicality on the road.
Advanced comfort systems: a tankless on-demand water heater, a 30,000 BTU ducted furnace, ducted air conditioning, ductwork with thermoplastic joiners, and optional in-floor heating ducts give reliable climate control year-round.
The 26RES comes ready for modern connectivity and entertainment: a rooftop omni-directional antenna with satellite pass-through, a multi-source signal controller, 12 V charging stations, interior LED HDTV and an entertainment center make it easy to stay connected and comfortable wherever you go.
