Three floor plans cover couples, small families, and shoppers who need the family-focused 38 KA with dedicated rear bunk beds, a rare configuration in the Class A DP category.
Freightliner XCR Chassis and Cummins L9
Every Allegro Red pairs the Freightliner XCR modular rail rear-engine chassis with the Cummins L9 380HP diesel (1,150 lb-ft) and the Allison 3000 MH 6-speed automatic. Standard chassis equipment includes full air brakes with automatic slack adjusters, a VGT engine brake, Freightliner V-Series front and rear air suspension, custom-tuned Sachs shocks, and front disc brakes.
The 38,320-pound GVWR, 48,320-pound GCWR, and 10,000-pound trailer hitch put the Allegro Red firmly in the heavy-duty DP segment. Note for used shoppers: the Cummins B6.7 360HP that was previously offered on the Allegro Red is no longer available on current-year builds, so verify the engine on any used unit before purchase.
Driver Assistance and Cockpit
Standard driver assistance includes adaptive cruise control, collision mitigation with forward warning and active braking, electronic stability control, automatic traction control, tire pressure monitoring, integrated side-view cameras with turn-signal activation, and a color backup camera on a 7-inch HD monitor.
The cockpit carries lifestyle leather power driver and passenger seats with swivel bases, a tilt and telescoping steering wheel with integrated controls, adjustable pedals, a one-piece panoramic windshield, and a powered solar and privacy windshield shade.
Hydronic Heating and Electronic Appliance Equipped (Optional All-Electric)
The Allegro Red is offered in two power configurations. The standard LP coach runs propane for the ducted furnaces, the Truma AquaGo instant water heater, and the three-burner LP cooktop.
The optional Hydronic Heating and Electronic Appliance Equipped configuration (formerly "All-Electric Coach") swaps those LP appliances for an Aqua-Hot 250D heat exchanger and a two-burner induction cooktop, removing the LPG tank entirely.
Off-Grid Power and Climate
Standard electrical is an 8.0-kW Onan Quiet Diesel generator on a slide tray, a 2,000-watt pure sine inverter/charger with auto-gen start, six 6-volt 225-Ah flooded lead-acid house batteries, and 50-amp shore power.
Optional upgrades include six 6-volt 210-Ah AGM batteries and two factory solar packages (200-watt single-panel or 600-watt three-panel array, both with 30-amp controllers). Dual 15,000-BTU rooftop A/Cs with heat pumps are standard.
Exterior and Coach Control
Every Allegro Red carries full-body paint with three layers of clear coat (four colors, two paint schemes), a Girard side-mounted powered patio awning with LED lighting, a Girard powered door awning, Girard slide-out toppers, frameless single-pane windows, an automatic double entry step, key fob entry, and chrome power heated side mirrors with integrated cameras.
Coach control runs through the Spyder Controls Multiplex System with the Firefly Integrations Mira Module. The Vegatouch app adds Bluetooth-range smartphone control of auto-gen start, lighting, climate, and tank monitoring.
Interior and Kitchen
Interior standard equipment across every floor plan includes handcrafted overhead cabinetry, a carpeted step well with a powered cover, dimmable LED lighting, soft-close drawers, solar and privacy shades, and a solid-surface galley countertop with full tile backsplash.
The kitchen carries a 1.7-cu-ft smart convection microwave with air fry and a double-bowl sink with pull-down sprayer. The 33 AA and 37 BA use a 20-cu-ft residential refrigerator; the 38 KA steps up to a 23-cu-ft French-door refrigerator. Options include a stacked washer/dryer, central vacuum, Gold Heat heated tile floor, and a standalone fireplace on the 33 AA and 38 KA.
Sleeping and Bath
Every Allegro Red carries a King-size mattress (72" x 80") in the master as standard, with an optional Queen (60" x 80") on the 37 BA and 38 KA. Every plan includes a mounted bedroom TV, a ceiling fan, and nightstands with solid-surface tops.
The 33 AA carries a single bath. The 37 BA and 38 KA step up to a bath-and-a-half (full bath with a 28.5" x 40.5" shower plus a half-bath with macerator toilet).
The 38 KA also carries dedicated rear passenger-side bunk beds (28" x 70") with tablet holders. Combined with the standard front cab-over drop-down bunk option, the 38 KA sleeps up to 8, a rare setup in the Class A DP segment.

Tiffin Allegro Red FAQs
What is the Tiffin Allegro Red?
The Tiffin Allegro Red is a Class A diesel pusher built on the Freightliner XCR chassis with the Cummins L9 380HP diesel. It's the entry-tier DP in Tiffin's lineup, aimed at family buyers and full-time travelers who want diesel chassis credentials at a lower price than the Phaeton or Allegro Bus.
What chassis is the Tiffin Allegro Red built on?
The Allegro Red is built on the Freightliner XCR rear-engine diesel chassis with the Cummins L9 380HP diesel (1,150 lb-ft) and the Allison 3000 MH 6-speed automatic. Standard equipment includes full air brakes with automatic slack adjusters, a VGT engine brake, Freightliner V-Series front and rear air suspension, Sachs shocks, and front disc brakes. Used shoppers: the Cummins B6.7 360HP that was previously offered is no longer available on current-year builds, so verify the engine on any used unit before purchase.
How much can the Tiffin Allegro Red tow?
Every Allegro Red carries a 10,000-pound trailer hitch. The 38,320-pound GVWR and 48,320-pound GCWR put it in the heavy-duty DP segment, so it comfortably tows a full-size toad, an enclosed trailer, or a boat.
What is the difference between the LP and Hydronic / All-Electric Allegro Red?
The standard LP coach runs propane for the furnace, water heater, and cooktop. The optional Hydronic Heating and Electronic Appliance Equipped configuration (formerly "All-Electric Coach") swaps the LP appliances for an Aqua-Hot 250D heat exchanger and an induction cooktop, removing the LPG tank entirely. Pick LP for simplicity and a lower entry price. Pick hydronic for all-electric cooking and no LP dependency.
What floor plans does the Tiffin Allegro Red come in?
The Allegro Red comes in three floor plans at MHSRV: the 33 AA (35'2", 4 slides, single bath, sleeps 4-6), the 37 BA (38'6", 3 slides, bath-and-a-half, sleeps 2-6), and the 38 KA (39'6", 3 slides, bath-and-a-half, sleeps 4-8, dedicated rear bunk beds). All three share the Freightliner XCR chassis, the Cummins L9 380HP, the 10,000-pound hitch, and the King master (Queen optional on 37 BA and 38 KA).
Does the Tiffin Allegro Red come in a bunk model floor plan?
Yes. The 38 KA is the family bunk model, with dedicated rear passenger-side bunk beds (28" x 70") and tablet holders. Combined with the optional front cab-over drop-down bunk, it sleeps up to 8. Class A diesel pushers with dedicated bunks are rare, which makes the 38 KA a real differentiator for family buyers.
Does the Tiffin Allegro Red come in a bath-and-a-half floor plan?
Yes. The 37 BA and 38 KA both carry a bath-and-a-half as standard (full bath with a 28.5" x 40.5" shower plus a half-bath with macerator toilet). The 33 AA carries a single bath with a 34.5" x 34.5" shower.
How does the Tiffin Allegro Red handle off-grid power?
Standard electrical is an 8.0-kW Onan Quiet Diesel generator on a slide tray, a 2,000-watt pure sine inverter/charger with auto-gen start, six 6-volt 225-Ah flooded batteries, and 50-amp shore power. Optional AGM battery upgrade and 200-watt or 600-watt factory solar packages are available for extended off-grid stays.
What's the difference between the Allegro Red and the Allegro Bus?
The Allegro Bus is Tiffin's flagship DP; the Allegro Red is the entry DP. The Allegro Bus runs the PowerGlide XC raised-rail chassis with a Cummins L9 450HP diesel (vs. Freightliner XCR with L9 380HP on the Allegro Red), carries standard hydronic all-electric, standard bath-and-a-half on every plan, standard Starlink, ZF independent front suspension, and offers tag-axle 45-foot floor plans with an optional Cummins X15 605HP. Pick the Allegro Red for a lower entry price, the 38 KA family bunks, and a shorter footprint. Pick the Allegro Bus for the flagship chassis, standard hydronic, and flagship ADAS/connectivity.
What's the difference between the Allegro Red and the Phaeton?
Both are Tiffin Class A DPs, but the Phaeton is the mid-tier DP that sits above the Allegro Red and below the Allegro Bus. The Phaeton carries a higher-content standard equipment package with more premium interior finishes and more standard content that's optional on the Allegro Red. Current-year specs on both models rotate, so verify with an MHSRV product expert. Pick the Allegro Red for the lower entry price and the 38 KA family bunk floor plan. Pick the Phaeton for the mid-tier standard package if you don't need bunks.
Do I need a CDL to drive the Tiffin Allegro Red?
Federal law exempts motorhomes from CDL requirements, so a commercial license is not required. However, the Allegro Red's 38,320-pound GVWR is above the 26,001-pound threshold that some states use for a non-commercial license class (California, Hawaii, Nevada, Wisconsin, and a handful of others). Rules vary by state and change over time, so check your state's DMV before purchase.
