The Tiffin® Phaeton® is a mid-luxury Class A diesel pusher built on the PowerGlide® XC raised-rail rear-engine diesel chassis with the standard Cummins® L9 450-horsepower diesel engine producing 1,250 lb-ft of torque. Shopping for a new Tiffin Phaeton or a used Tiffin Phaeton? MHSRV stocks one of the largest selections of Tiffin Phaeton motorhomes for sale anywhere in the country, all backed by industry-leading discount pricing.
The Tiffin Phaeton sits in the mid-luxury tier of the Tiffin Class A diesel pusher lineup, between the entry-tier Allegro Red and the flagship Allegro Bus. It's suited for buyers who want serious diesel pusher chassis credentials, premium interior amenities, and Tiffin's signature handcrafted cabinetry without stepping all the way up to the Allegro Bus's flagship pricing. With four distinct floor plans ranging from 37'9" to 45' long (including a tag-axle 44 OH for buyers who want a full 45-foot luxury coach), the Phaeton has a layout for nearly every kind of luxury Class A buyer.
One of the most notable updates for the 2026 Phaeton is the now-standard Cummins L9 450HP diesel engine across the entire lineup, replacing the lower-horsepower options previously offered on shorter floor plans. The 2026 Phaeton also introduces three new interior decor packages (Gelato, Titanium, Mesa), updated tile flooring options including a Gold Heat® dual-zone heated tile floor option, and the optional Pet Perks Package for pet owners (which includes a pet dish holder and leash holder at the entrance door).
Under the hood, every Phaeton 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, Freightliner® V-Series V-Ride rear suspension, custom-tuned Koni® shock absorbers, front disc brakes with rear drum brakes, hydraulic leveling jacks with control panel, and front/rear 295/80R 22.5 tires. The 44 OH floor plan adds a steerable tag axle for tighter turning radius and additional load capacity, with a 46,000-pound GVWR and 56,000-pound GCWR (vs. 40,000 GVWR and 50,000 GCWR on the shorter floor plans).
Standard advanced driver assistance features on the Phaeton include adaptive cruise control, automatic traction control, electronic stability control, collision mitigation with forward warning and active braking, tire pressure monitoring, side-view cameras integrated within the side-view mirrors and activated by turn signals, a color backup camera, and a 10-inch high-definition LED multichannel camera monitor. Optional driver assistance features include a blind spot monitoring system, in-dash navigation system, and an electric front overhead drop-down bunk for additional guest sleeping. The cockpit also includes lifestyle leather power driver and passenger seats with swivel bases and integrated seat belts, a tilt and telescoping steering wheel with integrated controls, adjustable accelerator and brake pedals, a wraparound dash with graphite accents, a digital dash cluster, and a passenger console wireless phone charger.
For coach configuration, the Phaeton offers two power options on the 35 CH, 37 BH, and 40 IH floor plans. The standard LP coach uses propane to power the ducted furnaces, 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® 450D heat exchanger and a two-burner induction cooktop, removing the LPG tank entirely. The 44 OH floor plan, by contrast, comes standard with the hydronic / all-electric configuration, with no LP option offered on this top-tier floor plan.
For electrical and off-grid capability, every Phaeton 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, an energy management system, and Starlink roof prep. Standard battery configuration is six 6-volt 225-amp-hour flooded lead-acid house batteries, with optional upgrades to six 6-volt 210-amp-hour extended cycle AGM or three 12-volt 270-amp-hour lithium house batteries. Solar prep with auxiliary docking ports comes standard, plus optional 600-watt (three 200-watt panels) or 1,200-watt (six 200-watt panels) rooftop solar packages on the 40 IH and 44 OH floor plans (the shorter floor plans only offer the 600-watt option).
Coach control is centralized through the Spyder Controls Multiplex System with the Firefly Integrations Mira Module. The system includes a centralized 10-inch main monitor, 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 Phaeton features full-body paint with four layers of clear coat, frameless dual-pane windows, a Girard® powered door awning with integrated LED lighting, a Girard® manual window awning package, Girard® slide-out toppers, side-swinging exterior storage doors with gas shocks, a powered fresh water hose retract reel, an exterior TV with soundbar, an automatic stainless steel double entry step, a keyless entry system for the front entrance and select compartment doors, chrome power heated side-view mirrors with integrated cameras, and a Lippert™ On-The-Go™ telescoping ladder. Six full-body paint colors are offered (Midnight Blue, Waterfall, NASA, Frosted Granite, Bordeaux, White Mahogany), available in two paint scheme options (Generation 11 or Generation 12). The Midnight Blue color includes black aluminum wheels for a more aggressive aesthetic. The standard side-mounted powered patio awning can be upgraded to dual Girard roof-mounted powered patio awnings with integrated LED lighting and a dual pitch feature.
Inside the Phaeton, every floor plan features handcrafted overhead cabinetry, a solid surface step well with a powered step well cover, recessed step well lighting, dimmable LED lighting, soft-close drawers, solar and privacy shades, a soft-touch vinyl ceiling, a central vacuum system with VacPan® automatic dustpan, prep for washer and dryer, and a 1.7-cubic-foot smart convection microwave with air fry. Three interior decor packages are offered (Gelato, Titanium, Mesa) tied to coordinated upholstery, cabinetry, and flooring options. Optional features include a stacked washer and dryer, a Gold Heat® dual-zone heated tile floor, a drawer-style dishwasher, and a standalone living area fireplace (exclusive to the 35 CH floor plan).
The Phaeton kitchen is built around a residential refrigerator (22-cubic-foot stainless steel French-door with bottom freezer on the 35 CH, stepping up to a 25-cubic-foot French-door unit on the 37 BH, 40 IH, and 44 OH), a double-bowl kitchen sink with single-lever faucet, pull-down sprayer, and built-in soap dispenser, galley overhead cabinets with pull-out drawers, full tile backsplash, task lighting, toe kick lighting, and a panoramic galley window. The 37 BH, 40 IH, and 44 OH floor plans also include a manual release Expand-An-Island for additional countertop and prep space.
For sleeping, every Phaeton 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. The 35 CH floor plan adds the Power Smart Lift bed mechanism as standard. Every floor plan includes overhead cabinets with headboard, a handcrafted privacy door, LED reading lights, nightstands with solid surface tops, a mounted bedroom TV, a centralized entertainment center, a ceiling fan, and a laundry hamper. The 35 CH and 40 IH feature floor-to-ceiling closet space, the 37 BH features a wardrobe with drawers underneath, and the 44 OH steps up to a walk-in closet. An optional bedroom egress door and an optional in-room safe are also available.
Bathroom configuration varies by floor plan. The 35 CH features a single bathroom with a 31.75" x 40" one-piece molded fiberglass shower, dual porcelain master bathroom sinks, a macerator toilet, and a medicine cabinet with tri-view vanity mirror. The 37 BH, 40 IH, and 44 OH all feature a bath-and-a-half layout, with a full bathroom plus a half-bath. The 37 BH uses a smaller 28.5" x 40.5" shower with a single porcelain sink and a mirrored medicine cabinet, while the 40 IH and 44 OH use the larger 31.75" x 40" shower with dual porcelain sinks and a tri-view vanity mirror. All bath-and-a-half floor plans include a gravity flush toilet in the main bathroom and a macerator toilet in the half-bath.
Tiffin Phaeton floor plans available at MHSRV include the Phaeton 35 CH (37'9" length, ~375 sq ft, 3 slides, sleeps 2-4, single bath, the most compact and couples-focused floor plan with the standard Power Smart Lift bed mechanism, optional standalone fireplace, and optional 600-watt solar package), 37 BH (38'2" length, ~375 sq ft, 3 slides, sleeps 2-6, bath-and-a-half, the standard mid-size floor plan now built on the new XSH chassis with increased basement storage and overall height vs. previous model years), 40 IH (41'4" length, ~405 sq ft, 4 slides, sleeps 2-6, bath-and-a-half, the spacious mid-size floor plan with the larger 31.75" x 40" shower and optional 1,200-watt solar package), and 44 OH (45' length, ~440 sq ft, 4 slides, sleeps 2-8, bath-and-a-half, the tag-axle flagship floor plan that comes standard with the all-electric hydronic configuration and walk-in closet).
Shopping the Tiffin Phaeton? You may also want to compare it against the rest of Tiffin's Class A diesel pusher lineup, including the Tiffin Allegro Bus (luxury-tier flagship that sits above the Phaeton with the larger Cummins L9 chassis options and additional standard features), the Tiffin Allegro Red (entry-tier diesel pusher), and the Tiffin Byway (most accessible diesel pusher tier). Buyers comparing diesel vs. gas Class A products may also want to look at the Tiffin Open Road Allegro, while buyers considering a Class C/Super C diesel alternative should compare against the Tiffin Allegro Bay, all available at Motor Home Specialist alongside the full Tiffin lineup.
Tiffin Phaeton FAQs
What is the Tiffin Phaeton?
The Tiffin® Phaeton® is a mid-luxury Class A diesel pusher built by Tiffin Motorhomes on the PowerGlide® XC raised-rail rear-engine diesel chassis with a standard Cummins® L9 450-horsepower diesel engine. The Phaeton sits in the mid-luxury tier of the Tiffin Class A diesel pusher lineup, between the entry-tier Allegro Red and the flagship Allegro Bus. It's well-suited for buyers who want serious diesel pusher chassis credentials, premium interior amenities, and Tiffin's signature handcrafted cabinetry at a more accessible price point than the Allegro Bus.
What chassis is the Tiffin Phaeton built on?
The Tiffin Phaeton is built on the PowerGlide® XC raised-rail rear-engine diesel chassis. 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, Freightliner V-Series V-Ride rear suspension, custom-tuned Koni shock absorbers, front disc brakes with rear drum brakes, and hydraulic leveling jacks with control panel. The 44 OH floor plan also adds a steerable tag axle for additional load capacity and a tighter turning radius.
What engine comes on the Tiffin Phaeton?
Every Tiffin Phaeton comes standard with the Cummins® L9 450-horsepower diesel engine, producing 1,250 lb-ft of torque (with peak horsepower achieved at 2,100 RPM and peak torque at 1,400 RPM), paired with the Allison 3000 MH 6-speed automatic transmission with lock-up torque converter. The Cummins L9 is now standard across the entire 2026 Phaeton lineup, replacing lower-horsepower options previously offered on shorter floor plans.
How much can the Tiffin Phaeton tow?
Every Tiffin Phaeton has a 10,000-pound trailer hitch with a 10,000-pound maximum trailer weight rating, regardless of floor plan. The 35 CH, 37 BH, and 40 IH have a 40,000-pound GVWR with a 50,000-pound GCWR, while the tag-axle 44 OH steps up to a 46,000-pound GVWR and 56,000-pound GCWR. This makes the Phaeton a strong choice for buyers who plan to tow a substantial toad vehicle, enclosed trailer, or boat behind the coach.
What is the difference between the LP and Hydronic / All-Electric Phaeton configurations?
The Tiffin Phaeton offers two power configurations on the 35 CH, 37 BH, and 40 IH floor plans. The standard LP coach uses propane to power the ducted furnaces, 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® 450D heat exchanger (which provides both heated air and heated water) and a two-burner induction cooktop, removing the LPG tank entirely. Notably, the 44 OH floor plan comes standard with the hydronic / all-electric configuration, with no LP option offered on this top-tier floor plan.
What floor plans does the Tiffin Phaeton come in?
The Tiffin Phaeton is available at MHSRV in four floor plans: the Phaeton 35 CH (37'9" length, ~375 sq ft, 3 slides, sleeps 2-4, single bath, the most compact couples-focused floor plan with standard Power Smart Lift bed mechanism and optional standalone fireplace), 37 BH (38'2" length, ~375 sq ft, 3 slides, sleeps 2-6, bath-and-a-half, the standard mid-size floor plan now built on the new XSH chassis), 40 IH (41'4" length, ~405 sq ft, 4 slides, sleeps 2-6, bath-and-a-half, the spacious mid-size floor plan with the larger shower and optional 1,200-watt solar package), and 44 OH (45' length, ~440 sq ft, 4 slides, sleeps 2-8, bath-and-a-half, the tag-axle flagship that comes standard with all-electric hydronic configuration and walk-in closet).
Does the Tiffin Phaeton come in a tag axle floor plan?
Yes. The 45-foot Phaeton 44 OH floor plan features a steerable tag axle, which provides a tighter turning radius than a standard 45-foot motorhome and adds load capacity for a higher 46,000-pound GVWR and 56,000-pound GCWR. The 44 OH is the flagship Phaeton floor plan and also comes standard with the all-electric hydronic configuration, the larger 25-cubic-foot French-door refrigerator, a walk-in closet, and a bath-and-a-half with the larger 31.75" x 40" shower and dual porcelain sinks.
Does the Tiffin Phaeton come in a bath-and-a-half floor plan?
Yes. Three of four Tiffin Phaeton floor plans (37 BH, 40 IH, 44 OH) feature a bath-and-a-half layout as standard equipment, with one full bathroom plus a half-bath. The 37 BH uses a 28.5" x 40.5" shower with a single porcelain master bathroom sink and a mirrored medicine cabinet, while the 40 IH and 44 OH use the larger 31.75" x 40" shower with dual porcelain sinks and a medicine cabinet with tri-view vanity mirror. All bath-and-a-half floor plans include a gravity flush toilet in the main bathroom and a macerator toilet in the half-bath. The more compact 35 CH floor plan, by contrast, features a single full bathroom with the larger 31.75" x 40" shower, dual porcelain sinks, a macerator toilet, and the tri-view medicine cabinet.
Does the Tiffin Phaeton come with solar?
Every Tiffin Phaeton comes standard with solar prep, including auxiliary docking ports for aftermarket solar panels and an auxiliary solar port. Two factory rooftop solar packages are offered as options: a 600-watt rooftop package (three 200-watt panels with a 30-amp controller) on every floor plan, and a 1,200-watt rooftop package (six 200-watt panels with two 30-amp controllers) on the larger 40 IH and 44 OH floor plans. Combined with the optional three 12-volt 270-amp-hour lithium house batteries, this delivers substantial off-grid capability for buyers who want to spend extended time boondocking or dry camping.
Does the Tiffin Phaeton come with a generator?
Yes. Every Tiffin Phaeton comes standard with a 10.0-kilowatt Onan® Quiet Diesel generator on a slide tray for easier service access, paired with a 3,000-watt pure sine wave inverter/charger with auto-gen start capability controlled through the Spyder Controls Multiplex System.
Does the Tiffin Phaeton come Starlink-prepped?
Yes. Every Tiffin Phaeton comes standard with Starlink roof prep, allowing buyers to add the optional Starlink® satellite internet system at any time without aftermarket modification (subscription required). The Wi-Fi booster is standard unless Starlink Pro is optioned, and the two systems are not combinable.
What is the bedroom like in the Tiffin Phaeton?
Every Tiffin Phaeton 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. The 35 CH floor plan adds the Power Smart Lift bed mechanism as standard. Every floor plan includes overhead cabinets with headboard, a handcrafted privacy door, LED reading lights, nightstands with solid surface tops, a mounted bedroom TV, a centralized entertainment center, a ceiling fan, and a laundry hamper. The 35 CH and 40 IH feature floor-to-ceiling closet space, the 37 BH features a wardrobe with drawers underneath, and the 44 OH steps up to a walk-in closet. An optional in-room safe and bedroom egress door are also available.
What is the difference between the Phaeton and Allegro Bus?
The Tiffin Allegro Bus sits above the Phaeton as the flagship luxury-tier Class A diesel pusher in the Tiffin lineup. Both share the PowerGlide XC chassis and the standard Cummins L9 450HP diesel engine, but the Allegro Bus offers additional flagship features, including: an optional Cummins X15 605HP engine upgrade on tag-axle floor plans, a wider GVWR range up to 52,000 pounds (vs. 46,000 on the Phaeton 44 OH), additional standard ADAS features including Mobileye lane departure warning and standard blind spot monitoring (vs. optional on Phaeton), standard Starlink satellite internet (vs. Starlink prep on Phaeton), standard Gold Heat heated tile floor (vs. optional on Phaeton), standard stacked washer and dryer (vs. optional on Phaeton), additional luxury cockpit features including the Tiffin PowerDrive adaptive steering column, and dual roof-mounted Girard awnings standard. The Phaeton, in turn, offers a more accessible price point while still delivering Cummins L9 450HP diesel power, the PowerGlide XC chassis, and Tiffin's signature handcrafted interior quality.
How much does a Tiffin Phaeton cost?
Final pricing on a new Tiffin Phaeton varies by floor plan, configuration (LP coach or hydronic / all-electric coach where available), interior decor package, exterior paint and paint scheme, and optional features (lithium battery upgrade, solar package, dishwasher, Gold Heat heated tile floor, stacked washer and dryer, blind spot monitoring, in-dash navigation, etc.).
