The 2026 Tiffin Allegro Bay 38AB is a rugged yet luxurious Super C diesel motorhome built on the reputable Freightliner S2RV chassis. Under the hood, it features a powerful Cummins B6.7 360 HP engine paired with an Allison 3000 MH 6-speed automatic transmission, delivering a robust 800 lb-ft of torque. With a GVWR of 33,000 lb and a towing capacity of up to 12,000 lb, this coach effortlessly handles heavy loads and sizeable trailers . The rugged underpinnings are complemented by advanced safety features such as full-time NoSPIN rear differential, automatic traction control, and BrakeSync, while hydraulic leveling jacks and air suspension ensure stability both on the move and at the campsite .
Inside, the 38 AB layout is designed for maximum comfort and flexibility with three opposing slide-outs that open wide to create a spacious living area. The front-rich lounge includes an air-coil sofa bed and booth dinette, with an optional overhead bunk for extra sleeping capacity—accommodating up to six. Practical conveniences abound: a residential-sized 20 cu ft stainless fridge, a convection microwave with air-fry features, a three-burner cooktop, and an "Expand-An-Island" countertop extension. The rear master suite offers a king-size bed slide-out, large wardrobe with drawers, and washer/dryer prep. The central bath features a roomy 28.5″x40.5″ shower and dual access for privacy .
No detail is overlooked in the Allegro Bay’s luxury appointments and utility systems. Tiffin’s tile floor option, handcrafted cabinetry, and tile backsplash add a refined aesthetic. Plumbing and comfort systems include a Truma AquaGo instant water heater, Onan Quiet Diesel 8 kW generator, dual 15,000 BTU A/C units with heat pump, and a 35,000 BTU furnace. Beneath the coach are 136 cu ft of pass-through storage, satellite and Starlink prep, exterior entertainment hookup, and a Girard power awning with LED lighting—all making it an ideal coach for families or couples who seek a premium travel experience .
