Adventure Meets Everyday Luxury!
Introducing the 2026 Keystone Montana 3123RL — the perfectly balanced luxury fifth wheel designed for couples, small families, and those who love to explore without giving up comfort. This beauty blends smart design with premium construction, and it’s now ready to roll at ArrKann RV Carstairs!
SPACIOUS REAR LIVING COMFORT
Step inside and breathe — the 3123RL features a thoughtfully designed rear living room with three slide-outs that create a roomy, welcoming environment. Settle in on plush seating around the entertainment center complete with a 50″ Smart TV and JBL sound system, or cozy up by the fireplace — the perfect backdrop for movie nights, games, and lazy mornings.
A KITCHEN YOU’LL LOVE
The heart of this coach is a mid-kitchen that feels like home. With a large island, solid surface countertops, and an 18 cu ft residential refrigerator with ice maker, you’ll have the space and tools to create meals just like in your house. A 3-burner stove and residential microwave make cooking easy, and generous pantry space keeps everything organized on the road.
REST EASY — THERE’S A ROOM FOR THAT
The front private bedroom is your personal escape after a day of adventure. Enjoy a king-size bed on a slide-out, plenty of storage, and washer/dryer prep for longer trips. The spacious bathroom boasts a residential shower with skylight and a stylish vanity — real comfort for real living.
BUILT TO GO FURTHER
Like all Montanas, the 3123RL doesn’t just look great — it’s engineered tough for seasons and roads alike:
Lifetime-ready 12″ I-beam chassis with z-frame technology
MORryde® suspension for a smoother tow
Insulated, heated underbelly for cold-weather camping
Fully walkable roof with Alpha seamless membrane
Durable MaxTurnâ„¢ front cap with automotive-grade paint
Beautiful hardwood cabinetry & Beauflor® vinyl flooring throughout
AMENITIES FOR ANY SEASON
With fresh/gray/black tank capacities that keep you comfortable on extended trips and 50 amp service for all your power needs, this Montana doesn’t just meet expectations — it raises them. And dual awnings with LED lighting make outdoor living an instant upgrade.
IN SUMMARY:
The 2026 Montana 3123RL is the sweet spot between luxury and livability. Whether it’s weekend escapes, seasonal stays, or bucket-list road trips, this fifth wheel delivers comfort, convenience, and durability in equal measure — all waiting for you at ArrKann RV Carstairs.
