Step into the 2026 Thor Motor Coach Aria 3901 and experience a diesel Class A motorhome designed for travelers who want space, sophistication, and effortless comfort. With three expansive slide outs, this coach opens into a residential-style retreat featuring captain’s chairs that swivel, a mid-coach half bath, and a rear full bath with dual sinks—perfect for long trips, guests, and everyday convenience.
Entertaining is easy and enjoyable thanks to generous seating and multiple seatbelts that let you bring everyone along. Relax in the Dream Dinette, stretch out on the tri-fold sofa, or unwind in the reclining theater seats. The living area invites cozy evenings with a fireplace and two LED TVs, creating the perfect atmosphere for movie nights or relaxing downtime.
Cooking becomes a pleasure with the well-equipped kitchen featuring a convection microwave oven, electric induction cooktop, and a 21.4 cu. ft. double-door residential refrigerator. A dedicated pantry ensures you have room for every ingredient. When the day winds down, retreat to the walk-through bedroom where the Tilt-A-View inclining king bed delivers customized comfort before you enter the spa-like full bathroom.
Behind the wheel, the Aria 3901 offers a driving experience as refined as its interior. Its VFS front axle with a 55-degree wheel cut, Air-Ride suspension, and Sachs shock absorbers create a smooth, confident ride. The driver enjoys a 10.1" touchscreen dash radio with Bluetooth and Sirius/XM prep, along with leatherette reclining/swivel captain’s chairs for premium comfort mile after mile.
Throughout the coach, high-end craftsmanship shines with Wyndham cabinetry, solid-surface countertops, designer tile backsplash, and a large double-bowl stainless steel sink with pull-down sprayer. From the oversized full-height shower to the thoughtfully designed storage solutions, the Aria 3901 elevates every aspect of RV living.
