Tiffin Allegro Bay Super C diesel motorhomes for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World. The Tiffin® Allegro Bay® is a Super C diesel motorhome (classified by Tiffin as a Class C) built on the heavy-duty Freightliner® S2RV chassis with a Cummins® B6.7 360-horsepower diesel engine producing 800 lb-ft of torque. Shopping for a new Tiffin Allegro Bay or a used Tiffin Allegro Bay? MHSRV stocks one of the largest selections of Tiffin Allegro Bay motorhomes for sale anywhere in the country, all backed by industry-leading discount pricing.
The Tiffin Allegro Bay is built for buyers who want serious diesel chassis credentials, residential luxury interior amenities, and the family-friendly cab-over bunk of a Class C platform paired with the heavy-duty diesel powertrain typically found in Class A diesel pushers. With a 12,000-pound trailer hitch, full air brakes, and Allison® 3000 MH 6-speed automatic transmission, the Allegro Bay handles long-haul travel, mountain grades, and substantial towing loads with confidence, making it a strong fit for full-time travel and serious touring.
Under the hood, the Tiffin Allegro Bay pairs the Freightliner S2RV chassis and Cummins B6.7 360HP diesel with a full air brake system, automatic traction control, Freightliner BrakeSync®, taper leaf front suspension, Freightliner Airliner® rear suspension with manual dump valve, custom-tuned Sachs® shock absorbers, an Eaton Tractech NoSPIN® differential, and a single-stage variable geometry turbocharger (VGT) engine brake. The 33,000-pound GVWR and 45,000-pound GCWR put the Allegro Bay firmly in the heavy-duty diesel motorhome category that buyers typically associate with Super C coaches.
One of the Allegro Bay's most distinctive features is its optional Hydronic Heating & Electronic Appliance Equipped coach configuration (formerly known as "All-Electric Coach"). This option replaces the standard ducted LP furnace, Truma AquaGo™ instant water heater, and three-burner LP cooktop with an Aqua-Hot® 250D heat exchanger and induction cooktops, eliminating the LPG tank entirely. For buyers who prefer all-electric cooking and hydronic heating for both interior space and water, this is a meaningful upgrade that's increasingly difficult to find in the diesel motorhome segment.
For electrical and off-grid capability, every Allegro Bay comes standard with an 8.0-kilowatt Onan® Quiet Diesel generator, a 2,000-watt pure sine wave inverter/charger with auto-gen start, dual 15,000-BTU air conditioners with heat pumps, and 50-amp shore power with a powered retract reel. The standard battery configuration is four 6-volt 210-amp-hour extended cycle AGM house batteries, with an optional upgrade to dual 12-volt 270-amp-hour lithium house batteries. An optional 600-watt rooftop solar charging system (three 200-watt panels with a 30-amp controller) is also available.
Coach control is centralized through the Spyder Controls Multiplex System with the Firefly Integrations Mira Module. The system includes a centralized 7.5-inch main monitor, an interior entryway color touchscreen, and additional Spyder color touchscreens throughout the coach. The accompanying Vegatouch app delivers Bluetooth-range smartphone control of coach functions including auto-gen start, lighting, climate, and water pump control.
On the exterior, the Allegro Bay features full-body paint with three layers of clear coat, frameless tinted windows, a Girard® side-mounted powered patio awning with integrated LED lighting, Girard® slide-out toppers, side-swinging exterior storage doors with gas shocks, GatorHyde-lined cargo walls and floor, an exterior TV with soundbar, and an automatic double entry step. The Allegro Bay is offered in seven full-body paint options, including Midnight Blue G2, Fire Opal G3, Bordeaux G3, Crimson Mist G3, Frosted Granite G3, Polar Frost G3, and White Mahogany G3.
Inside the Tiffin Allegro Bay, every floor plan features handcrafted overhead cabinetry with honeycomb-patterned glass, dimmable LED lighting, soft-close drawers, solar and privacy shades, a soft-touch vinyl ceiling, a solid-surface galley countertop with full tile backsplash, a 20-cubic-foot stainless steel residential refrigerator with top freezer, a 1.7-cubic-foot smart convection microwave with air fry, and a double-bowl kitchen sink with single-lever faucet and pull-down sprayer. An optional drawer-style dishwasher is available across the lineup. The 2026 Allegro Bay also introduces new tile flooring options (Articulo White Polished or Weathered Beige Matte) tied to interior decor packages including Vapor, Morocco, and the Adobe Pendleton National Parks Collection.
For sleeping, every Allegro Bay floor plan features a memory foam King mattress (72" x 80") in the master bedroom as standard, with a memory foam Queen (60" x 80") available as an option. Every floor plan also includes the standard front overhead bunk with privacy curtains and telescoping ladder, supporting up to 300 pounds for additional guest sleeping. The handcrafted privacy door, mounted bedroom TV, ceiling fan, and centralized entertainment center (which houses the Blu-ray player, satellite receiver, and cable TV hookup) come standard across the lineup.
The driver's compartment includes Mitchell® Lifestyle Leather pneumatic suspension seats for both driver and passenger with dual armrests, lumbar support, and tilt/fore-aft/backrest/height adjustment, plus a leather-wrapped tilt and telescoping steering wheel, an ergonomic dash with woodgrain accents, side-view cameras, color backup camera, and a 10-inch detachable touchscreen with media center, AM/FM/satellite radio, Bluetooth®, navigation, and camera monitoring. A cab skylight and air horn with pull-cord come standard.
Tiffin Allegro Bay floor plans available at MHSRV include the Allegro Bay 38 AB, 38 BB, and 34 DB. The 38 AB (39'4" length, ~310 sq ft, 3 slides, sleeps 4-6) is the family-focused floor plan, with the largest seat belt configuration (6-8 belts) and the standard 74-inch DE sofa bed plus 75-inch booth dinette-sleeper for maximum sleeping capacity. The 38 BB (39'4" length, ~315 sq ft, 3 slides, sleeps 3-5) is the luxury flagship of the lineup, featuring a bath-and-a-half layout, a 74-inch air coil sofa bed with furniture-mounted swivel tables, and heated fresh and holding tank compartments via heat duct (vs. tank pads on the other floor plans).

Tiffin Allegro Bay FAQs
What is the Tiffin Allegro Bay?
The Tiffin® Allegro Bay® is a Super C diesel motorhome built by Tiffin Motorhomes on the heavy-duty Freightliner® S2RV chassis. Tiffin classifies the Allegro Bay as a Class C in their own marketing, but in industry terminology and at MHSRV, it sits in the Super C category, combining the cab-over body style of a Class C with the heavy-duty diesel chassis and substantially higher towing capability typically found in Class A diesel pushers. It's well-suited for everything from extended cross-country travel to full-time RV living.
Is the Tiffin Allegro Bay a Class C or a Super C?
The answer depends on who's classifying it. Tiffin Motorhomes positions the Allegro Bay as a Class C diesel motorhome in their own marketing materials, since it features the cab-over body style traditionally associated with Class C coaches. However, in industry terminology used by MHSRV and most other dealers, the Allegro Bay falls into the Super C category, which combines a Class C body style with the heavy-duty diesel chassis and substantially higher towing capability typically associated with Class A diesel pushers. The Allegro Bay's Freightliner S2RV chassis, Cummins B6.7 diesel engine, full air brake system, and 12,000-pound trailer hitch all align with the Super C category that Thor, Newmar, and other manufacturers use for similar products. Whether you're searching for a Class C or a Super C, the Allegro Bay is worth considering.
What chassis is the Tiffin Allegro Bay built on?
The Tiffin Allegro Bay is built on the Freightliner® S2RV chassis, powered by a Cummins® B6.7 360-horsepower diesel engine producing 800 lb-ft of torque, paired with an 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, Freightliner BrakeSync®, automatic traction control, custom-tuned Sachs® shock absorbers, an Eaton Tractech NoSPIN® differential, taper leaf front suspension, Freightliner Airliner® rear air suspension with manual dump valve, and a variable geometry turbocharger (VGT) engine brake.
How much can the Tiffin Allegro Bay tow?
The Tiffin Allegro Bay has a tow rating of 12,000 pounds at the trailer hitch, with a 12,000-pound maximum trailer weight rating, well beyond what most Class A and Class C gas motorhomes can handle. The 33,000-pound GVWR and 45,000-pound GCWR also place the Allegro Bay among the most capable motorhomes in the diesel segment, making it a strong choice for buyers who plan to tow a substantial toad vehicle, enclosed trailer, boat, or other heavy loads behind the coach.
What is the difference between the LP and Hydronic / All-Electric Allegro Bay configurations?
The Tiffin Allegro Bay is available in two power configurations. The standard LP coach uses propane to power the ducted furnace, the Truma AquaGo™ instant water heater, and the three-burner LP cooktop. The optional Hydronic Heating & Electronic Appliance Equipped configuration (formerly known as "All-Electric Coach") replaces the LP appliances with an Aqua-Hot® 250D heat exchanger (which provides both heated air and heated water) and a two-burner induction cooktop, removing the LPG tank entirely. Buyers who prefer all-electric cooking, hydronic heating, and reduced LP dependency typically choose the hydronic configuration, while buyers who prefer the simplicity and consistency of LP appliances typically choose the standard LP coach.
What floor plans does the Tiffin Allegro Bay come in?
The Tiffin Allegro Bay is available at MHSRV in three floor plans: the Allegro Bay 38 AB (39'4" length, ~310 sq ft, 3 slides, sleeps 4-6, single bath, family-focused with maximum sleeping and seat belt capacity), 38 BB (39'4" length, ~315 sq ft, 3 slides, sleeps 3-5, bath-and-a-half luxury layout), and 34 DB (35'7" length, ~250 sq ft, 2 slides, sleeps 3-4, more compact couples-focused layout with optional Murphy bed sofa).
Does the Tiffin Allegro Bay come with solar?
The Tiffin Allegro Bay comes solar-prepped with docking ports for aftermarket solar panels as a standard option, and an optional 600-watt rooftop solar charging system (three 200-watt panels with a 30-amp controller) is also available for buyers who plan to spend extended time off-grid. Combined with the optional dual 12-volt 270-amp-hour lithium house battery upgrade, this delivers substantial off-grid capability for buyers who want to spend extended time boondocking or dry camping.
Does the Tiffin Allegro Bay come with a generator?
Yes. Every Tiffin Allegro Bay comes standard with an 8.0-kilowatt Onan® Quiet Diesel generator, paired with a 2,000-watt pure sine wave inverter/charger with auto-gen start capability controlled through the Spyder Controls Multiplex System. This delivers reliable AC power for off-grid stays beyond the capabilities of the rooftop solar system alone.
Does the Tiffin Allegro Bay come in a bath-and-a-half floor plan?
Yes. The Tiffin Allegro Bay 38 BB is the bath-and-a-half floor plan in the Allegro Bay lineup, featuring a full bathroom plus a half-bath for added convenience on extended trips and full-time travel. The 38 BB also includes an electric gravity flush toilet and a macerator toilet (one of each), giving owners flexibility for different sewer hookup situations.
What is the bedroom like in the Tiffin Allegro Bay?
Every Tiffin Allegro Bay floor plan features a memory foam King-size mattress (72" x 80") in the master bedroom as standard, with a memory foam Queen (60" x 80") available as an option. Every floor plan also includes a handcrafted privacy door, LED reading lights, nightstands with solid surface tops, a mounted bedroom TV, a ceiling fan, a centralized entertainment center, and a wardrobe with drawers underneath. An optional bedroom egress door is available across the lineup. Every Allegro Bay also includes the front cab-over overhead bunk with privacy curtains and telescoping ladder, supporting up to 300 pounds for additional guest sleeping.
How much does a Tiffin Allegro Bay cost?
