Shopping for a new Tiffin Allegro Bus or a used Tiffin Allegro Bus? MHSRV stocks one of the largest selections of Tiffin Allegro Bus motorhomes for sale anywhere in the country, all backed by industry-leading discount pricing.
The Tiffin Allegro Bus sits at the top of the Tiffin Motorhomes lineup, suited for buyers who want a luxury-tier Class A diesel pusher with serious chassis credentials, premium interior amenities, and the confidence that comes with full air ride suspension, ZF independent front suspension, and an extensive standard advanced driver assistance suite. With five distinct floor plans ranging from 38 to 45 feet long, the Allegro Bus delivers a layout for nearly every kind of luxury Class A buyer, from couples-focused floor plans to family-friendly mid-bunk configurations.
One of the most notable upgrades for the 2026 Allegro Bus is the introduction of the new Tiffin PowerDrive adaptive steering column with integrated controls, delivering enhanced handling, drivability, and maneuverability over previous Allegro Bus model years. PowerDrive joins an already-substantial standard advanced driver assistance package, including adaptive cruise control, automatic traction control, electronic stability control, Mobileye® lane departure warning, automatic high beam headlight control, collision mitigation with forward warning and active braking, blind spot monitoring, tire pressure monitoring, and a 10-inch glass panel camera monitor with side-view cameras and color backup camera.
Under the hood, every Allegro Bus is built on the PowerGlide XC raised-rail rear-engine diesel chassis, paired with the Cummins L9 450HP diesel and the Allison® 3000 MH 6-speed automatic transmission with lock-up torque converter. Standard chassis features include a full air brake system with automatic slack adjusters, three-stage compression brake, ZF independent front suspension, Reyco® Granning® air ride rear suspension, custom-tuned Koni shock absorbers, front disc brakes, and front/rear 315/80R 22.5 tires. The 45-foot 45 BP, 45 OPP, and 45 BTP floor plans add a steerable tag axle for tighter turning radius and additional load capacity. Buyers who want substantially more power and torque can option the Cummins X15 605HP diesel engine on tag-axle floor plans, which upgrades the chassis to the heavy-duty PowerGlide SL platform.
For trailering, the 36 AP and 40 IP feature a 10,000-pound trailer hitch, while the 45 BP, 45 OPP, and 45 BTP step up to a 15,000-pound hitch. The GCWR also scales with floor plan: 52,000 pounds on the 36 AP and 40 IP, and 67,000 pounds on the 45-foot tag-axle floor plans. The 100-gallon fresh water tank, 100-gallon grey water tank, 55-gallon black water tank, and 150-gallon fuel tank make the Allegro Bus well-suited for extended off-grid stays and long-haul travel without frequent refueling or dump stops.
The Tiffin Allegro Bus comes standard with the Hydronic Heating & Electronic Appliance Equipped coach configuration (formerly known as "All-Electric Coach"). Space heating, water heating, and cooking appliances are all electrically powered, with an Aqua-Hot® 450D heat exchanger handling both interior heating and water heating, and a two-burner induction cooktop standard (with an optional Wolf® induction cooktop upgrade). This is a key differentiator from the Allegro Bay, where the hydronic configuration is optional rather than standard.
For electrical and off-grid capability, every Allegro Bus comes standard with a 10.0-kilowatt Onan® Quiet Diesel generator on a slide tray, a 3,000-watt pure sine wave inverter/charger with auto-gen start, three 15,000-BTU low-profile air conditioners with heat pumps and condensation drains, 50-amp shore power with a powered retract reel, and Starlink® satellite internet (subscription required). Standard battery configuration is six 6-volt 230-amp-hour flooded lead-acid house batteries, with optional upgrades to six 6-volt 300-amp-hour extended cycle AGM or three 12-volt 270-amp-hour lithium house batteries. Solar prep with auxiliary docking ports comes standard, and the Allegro Bus is offered with two solar package upgrades: 600-watt (three 200-watt panels with a 30-amp controller) or 1,200-watt (six 200-watt panels with two 30-amp controllers).
Coach control is centralized through the Spyder Controls Multiplex System with the Firefly Integrations Eclipse Module. The system includes a centralized 10-inch main monitor (larger than the 7.5-inch Allegro Bay system), a passenger console color touchscreen, an interior entryway color touchscreen, an exterior color touchscreen, and additional Spyder color touchscreens throughout the coach. The accompanying Vegatouch app delivers both Bluetooth-range local control and remote internet-based control of coach functions (including a free 90-day remote access trial).
On the exterior, the Allegro Bus features full-body paint with four layers of clear coat (vs. three on the Allegro Bay), striped slide-out endwalls, frameless dual-pane windows, fog lights and daytime running lights, exterior ground effects lighting, dual Girard® roof-mounted powered patio awnings with integrated LED lighting and dual pitch feature, a Girard® powered window awning package, a Girard® powered door awning, exterior lighting under the slide-out, an exterior TV with soundbar, a basement freezer, a powered fresh water hose retract reel, and a keyless entry system for the front entrance and select compartment doors. Five full-body paint colors are offered (Cinderwood, Arctic Sapphire, White Mahogany, Waterfall, Frosted Granite), available in two paint scheme options (Generation 13 or Generation 15).
Inside the Allegro Bus, every floor plan features handcrafted overhead cherry and maple cabinetry, a solid surface step well with tile inserts and a powered step well cover, recessed step well lighting, dimmable LED lighting, powered solar and privacy shades, soft-close drawers, a soft-touch vinyl ceiling, a central vacuum system with VacPan® automatic dustpan, Gold Heat® dual-zone heated tile floors, a stacked washer and dryer (standard, not optional), a 25-cubic-foot stainless steel residential refrigerator with French doors and bottom freezer, a drawer-style dishwasher (standard), and a 1.7-cubic-foot smart convection microwave with air fry. Three interior decor packages are offered (Pacifica, Omnia, Taos), with the 45 BTP floor plan featuring an exclusive Great Smoky Mountains decor package and Savoir Porcelain Tile flooring.
For sleeping, every Allegro Bus floor plan features a memory foam King mattress (72" x 80") with Power Smart Lift in the master bedroom as standard. Every floor plan includes a handcrafted privacy door, LED reading lights, nightstands with solid surface tops, a mounted bedroom TV, a centralized entertainment center, a ceiling fan, a decorative handcrafted wood ceiling ring, and an in-room safe. The 36 AP and 40 IP floor plans feature floor-to-ceiling closet space, while the 45-foot 45 BP, 45 OPP, and 45 BTP floor plans step up to a walk-in closet with solid surface countertops within the storage spaces. An optional bedroom fireplace and bedroom egress door are also available.
The Allegro Bus driver's compartment is loaded with luxury features, including power driver and passenger seats with swivel bases, integrated seat belts, lumbar support, the new Tiffin PowerDrive adaptive steering column with integrated controls, adjustable accelerator and brake pedals, a Valid™ liquid crystal display instrument cluster with integrated leveling controls, an ergonomic dash with carbon fiber accents, a passenger console wireless phone charger, a one-piece panoramic windshield, powered solar and privacy windshield shade, ceiling-mounted speakers, a JBL® sound system with amplifier and dual subwoofers, in-dash navigation via the Advanced Monitor System's 10-inch glass panel touchscreen, and a 7-inch passenger console touchscreen.
Every Allegro Bus floor plan includes a bath-and-a-half layout (one full bathroom plus a half-bath) as standard, featuring dual porcelain master bathroom sinks, a teak folding shower seat, a shower skylight, an LED shower light with sliding cover, a medicine cabinet with tri-view vanity mirror, an electric gravity flush toilet in the main bathroom, and a macerator toilet in the half-bath. The 36 AP and 40 IP feature a 32" x 40" solid-surface shower with inlaid tile and residential glass door, while the 45-foot 45 BP, 45 OPP, and 45 BTP step up to a larger 32" x 48" shower of the same construction.

Tiffin Allegro Bus FAQs
What is the Tiffin Allegro Bus?
The Tiffin® Allegro Bus® is the luxury-tier flagship Class A diesel pusher in Tiffin Motorhomes' lineup. It's built on the exclusive PowerGlide® XC raised-rail rear-engine diesel chassis with a standard Cummins® L9 450-horsepower diesel engine (with an optional Cummins X15 605HP upgrade on tag-axle floor plans), full air ride suspension, ZF independent front suspension, and an extensive standard advanced driver assistance package. The Allegro Bus sits at the top of the Tiffin lineup, above the Phaeton and Allegro Red, and is suited for full-time travelers and luxury Class A buyers who want maximum chassis credentials and premium interior amenities.
What is the new PowerDrive feature on the 2026 Allegro Bus?
PowerDrive is Tiffin's new-for-2026 adaptive steering column with integrated controls, delivering enhanced handling, drivability, and maneuverability over previous Allegro Bus model years. Tiffin's tagline for the upgrade is "Drive with Power," reflecting the system's role in giving Allegro Bus drivers more confidence behind the wheel of a 38-to-45-foot Class A diesel pusher. PowerDrive joins an already-substantial standard advanced driver assistance package on the Allegro Bus.
What chassis is the Tiffin Allegro Bus built on?
The Tiffin Allegro Bus is built on the exclusive PowerGlide® XC raised-rail rear-engine diesel chassis (or the heavier-duty PowerGlide SL on tag-axle floor plans optioned with the Cummins X15 engine). Standard chassis features include the Cummins L9 450HP diesel engine, Allison 3000 MH 6-speed automatic transmission, full air brake system with automatic slack adjusters, three-stage compression brake, ZF independent front suspension, Reyco Granning air ride rear suspension, custom-tuned Koni shock absorbers, front disc brakes, integrated Valid air leveling system with hydraulic leveling jacks, and a steerable tag axle on the 45-foot floor plans (45 BP, 45 OPP, 45 BTP).
What engine options are available on the Tiffin Allegro Bus?
The standard engine on every Tiffin Allegro Bus is the Cummins® L9 450-horsepower diesel producing 1,250 lb-ft of torque, paired with the Allison 3000 MH 6-speed automatic transmission. The 45-foot tag-axle floor plans (45 BP, 45 OPP, 45 BTP) offer an optional upgrade to the Cummins® X15 605-horsepower diesel producing 1,950 lb-ft of torque, which also upgrades the chassis to the PowerGlide SL platform. The X15 upgrade is targeted at buyers who plan to tow heavy loads or spend significant time in mountain terrain.
How much can the Tiffin Allegro Bus tow?
The Tiffin Allegro Bus tow rating varies by floor plan. The 36 AP and 40 IP have a 10,000-pound trailer hitch and a 10,000-pound maximum trailer weight rating, with a 52,000-pound GCWR. The 45-foot tag-axle floor plans (45 BP, 45 OPP, 45 BTP) step up to a 15,000-pound trailer hitch and a 15,000- to 20,000-pound maximum trailer weight rating depending on floor plan, with a 67,000-pound GCWR. This makes the Allegro Bus a strong choice for buyers who plan to tow a substantial toad vehicle, enclosed trailer, or boat behind the coach.
Is the Tiffin Allegro Bus all-electric?
Yes. The Tiffin Allegro Bus comes standard with the Hydronic Heating & Electronic Appliance Equipped configuration (formerly known as "All-Electric Coach"). Space heating, water heating, and cooking appliances are all electrically powered, with an Aqua-Hot® 450D heat exchanger handling both interior heating and water heating, and a two-burner induction cooktop standard (with an optional Wolf® induction cooktop upgrade). This is a key differentiator from the Allegro Bay, where the hydronic configuration is optional rather than standard.
What floor plans does the Tiffin Allegro Bus come in?
The Tiffin Allegro Bus is available at MHSRV in five floor plans: the Allegro Bus 36 AP (38'2" length, ~365 sq ft, 4 slides, 42K GVWR, the most compact couples-focused floor plan), 40 IP (41' length, ~405 sq ft, 4 slides, 42K GVWR, the mid-size floor plan), 45 BP (45' length, ~440 sq ft, 4 slides, 52K GVWR with steerable tag axle, sleeps up to 8 with the standard power drop-down mid-bunk for families), 45 OPP (45' length, ~440 sq ft, 4 slides, 52K GVWR with steerable tag axle, an open-plan layout with no mid-bunk for buyers who prefer maximum living space), and 45 BTP (45' length, ~440 sq ft, 3 slides, 52K GVWR with steerable tag axle, a special-edition floor plan featuring the exclusive Great Smoky Mountains decor package).
Does the Tiffin Allegro Bus come in a tag axle floor plan?
Yes. The 45-foot Allegro Bus floor plans (45 BP, 45 OPP, and 45 BTP) all feature a steerable tag axle, which provides a tighter turning radius than a standard 45-foot motorhome and adds load capacity for a higher 52,000-pound GVWR and 67,000-pound GCWR. The steerable tag axle also adds drive and tag axle drum brakes for additional stopping power on heavily-loaded coaches.
Does the Tiffin Allegro Bus come in a bunk model floor plan?
Yes. The Tiffin Allegro Bus 45 BP is the family-friendly floor plan in the Allegro Bus lineup, featuring a standard power drop-down mid-bunk on the passenger side that gives the 45 BP a sleeping capacity of up to 8. Buyers who'd prefer to swap the mid-bunk for a workspace can option a storage area with desk in place of the mid-bunk on the 45 BP floor plan.
Does the Tiffin Allegro Bus come with solar?
Every Tiffin Allegro Bus comes solar-prepped with auxiliary docking ports for aftermarket solar panels as standard equipment.
