Our Customers Say It Best

2026 Tiffin Allegro Bus Features

Cruise with class

The Allegro Bus is powered by a custom Tiffin PowerGlide XC chassis and offers two engine options: a 450-hp Cummins L9 or an optional 605-hp upgrade. You can expect tighter turns, better handling, and far less driver fatigue thanks to Tiffin’s integrated RoadWatch safety suite, which includes adaptive cruise control, electronic stability, and roll traction support. Dual-side fuel and DEF access make pit stops quicker, while the extended frame rail adds structure and balance.
Impressive interior

Things feel shiny and new once you step inside, thanks to new wall coverings, updated furniture materials, and elegant tile flooring, which give the 2026 interior a refined feel. Choose from coordinated décor themes, such as Pacifica or Taos, or opt for two-tone cabinetry with white linen upper cabinets for a brighter, more open look. Every finish, from countertops to backsplashes, has a sense of class without being cliché.
Fantastic new floor plans

This year’s Allegro Bus is offered in two expansive layouts: the 40 IP and the 45 OPP. Both layouts feature a 72" x 80" Power Smart king bed, dual lavatories, and washer/dryer setups. The 45 OPP stretches to 45 feet and offers a larger shower, extra cabinetry, and more living room space. Extras, you ask? Well, add theater seating, a kitchen island with a dinette bar, or even a rear egress door. The 40 IP provides all the essentials with a slightly more compact footprint of 41 feet, while still offering slide-out living and, of course, tons of storage.
Sizzle and serve

Every Allegro Bus features a full-size kitchen, complete with a drawer-style dishwasher, residential refrigerator, convection microwave, and an upgraded galley faucet. The countertop extension, pull-out storage, and optional 12" beverage center give you plenty of prep space. The 45 OPP allows for even more configuration flexibility, like a dinette with chairs, a U-shaped booth, or theater seating near the lift TV.
Your restful retreat

In the bedroom, you’ll find built-in nightstands, overhead cabinets, and a floor-to-ceiling closet (talk about space). Depending on the layout you opt for, you can sneak in smart add-ons like a wall safe, slide-out drawers, or even a window right above the pillows. The king bed is standard, but you can level up with a Power Smart version that shifts into the perfect position you desire with just one button.
No bathroom rush

Each Allegro Bus includes a spacious full bath and an additional lavatory. In the 45 OPP, the main shower measures 32" x 48" and offers more floor space. The 40 IP features a slightly more compact shower but maintains high-end fixtures and smart layout choices. Independent power shades, matte black towel bars, and tri-view mirrors complete the spa-inspired vibe.
