2026 Tiffin Allegro Bay Features

Tiffin
Disclaimer: The features below might not reflect what exactly will be on the vehicle.
  • Exterior view of the 2026 Allegro Bay in Fire Opal

    It’s adventure time

    The always dependable Freightliner® S2RV chassis powers the Allegro Bay, paired with a Cummins 360-hp diesel engine. Whether you’re towing a Jeep through the mountains or cruising into a lakeside campground, the ride is steady, the torque is strong, and the 12,000-pound towing capacity means nothing gets left behind.
  • Dinette and entertainment center inside the Allegro Bay

    Lounge life, upgraded

    Across all three 2026 floor plans, the Allegro Bay offers different arrangements to meet your taste. Depending on your floor plan, you’ll find super comfy theater seating, a sleeper sofa, or both, all in proximity to the TV and electric fireplace. The 38 BB leans into rear-bath spaciousness, while the 38 AB’s quad slides open up the front lounge in a big way. The new 34 DB proves you can downsize slightly without losing your hosting edge.
  • Kitchen inside the Allegro Bay

    No dinner reservations

    Forget the microwave-ready meals; you’ll be inspired to cook with your new solid-surface countertops, a full-size refrigerator, a convection microwave, plus a spacious pantry to keep your seasonings. Ample cabinet space and quiet-close drawers keep things tidy, so you can prep, serve, and clean up without worrying that dinner will become too cumbersome.
  • Bedroom inside the Allegro Bay

    Snooze the day away

    Regardless of which floor plan you choose, the bedroom serves as a private place to hide away. The 34 DB features a walk-around queen bed with an optional washer/dryer tucked across from it. Meanwhile, the 38 BB and 38 AB give travelers the option to stretch out with a king, along with built-in wardrobes, nightstands, and overhead storage. For added flexibility, the booth-dinette sleeper, DE sofa bed, and optional overhead bunk offer extra spots for family or guests to sleep comfortably.
  • Washer and dryer inside the Allegro Bay

    Rinse and repeat

    The 2026 Tiffin Allegro Bay takes its bathroom space seriously. You’ll find glass shower doors, natural skylight lighting, washer/dryer combo, and porcelain toilets. The 34 DB includes a handy mid-coach half bath, while the larger models offer spacious rear bathrooms with smart storage solutions and all the elbow room you could ever need.
