Tiffin Byway Class A Diesel Pusher Motorhomes For Sale
Tiffin Byway Class A diesel pusher motorhomes for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World. The Tiffin Byway is a Class A diesel pusher built on the Freightliner XCS straight-rail rear-engine chassis with the standard Cummins B6.7 340HP diesel producing 700 lb-ft of torque. MHSRV stocks one of the largest selections of new and used Tiffin Byway motorhomes for sale in the country, all backed by industry-leading discount pricing.
The Byway is the most accessible Class A diesel pusher in the Tiffin Motorhomes lineup, sitting below the entry-tier Allegro Red, the mid-tier Phaeton, and the flagship Allegro Bus. It's designed for first-time diesel pusher buyers, families, and travelers who want the smooth ride and Cummins-Freightliner credentials of a diesel pusher without the larger footprint of a 38-to-45-foot luxury coach.
Three floor plans (33 FL, 38 BL, 38 CL) span couples-focused, family-friendly, and luxury-leaning configurations. The 38 BL is one of the few Class A diesel pushers on the market at this price tier with two full bathrooms (not a bath-and-a-half), making it a real value for families and traveling groups.
Chassis, Powertrain, and Towing
Every Byway rides on the Freightliner XCS straight-rail rear-engine diesel chassis with the Cummins B6.7 340HP diesel (700 lb-ft of torque), paired with the Allison 2500 MH 6-speed automatic transmission with lock-up torque converter.
Standard chassis equipment includes a full air brake system with automatic slack adjusters, a single-stage VGT engine brake, Freightliner VFS air-ride front suspension, Freightliner V-Series V-Ride rear suspension, custom-tuned Sachs shock absorbers, hydraulic leveling jacks, front disc brakes with rear drum brakes, automatic traction control, tire pressure monitoring, and 255/70R 22.5 16-ply tires.
The 29,800-lb GVWR, 33,000-lb GCWR, and 5,000-lb trailer hitch put the Byway in the lighter-duty diesel pusher category, suited to towing a small toad vehicle or utility trailer rather than the heavy tow loads a tag-axle coach handles.
Driver-Assist and Cockpit
Standard cockpit features include lifestyle leather power driver and passenger seats with swivel bases, dual armrests, a passenger seat footrest, a tilt and telescoping steering wheel with integrated controls, adjustable accelerator and brake pedals, a digital dash cluster, mounted dash fans, and a one-piece panoramic windshield.
Side-view cameras integrated into the mirrors activate with the turn signals, and a 7-inch HD multichannel monitor pairs with the color backup camera. In-dash navigation and a powered solar and privacy windshield shade are standard.
Off-Grid: Solar Prep, Batteries, Generator
Every Byway carries an 8-kW Onan Quiet Diesel generator on a slide tray, a 2,000-watt pure sine wave inverter/charger with auto-gen start, dual 15,000-BTU A/Cs with heat pumps, dual ducted furnaces (35,000-BTU + 30,000-BTU), 50-amp shore power, and four 6-volt 225 Ah flooded lead-acid house batteries.
Solar prep with auxiliary docking ports is standard, plus an auxiliary solar port for portable panels. Tiffin doesn't currently offer a factory rooftop solar package on the Byway, but buyers can add aftermarket panels post-purchase. Optional connectivity upgrades include an in-motion satellite dish, a Wi-Fi booster, and Starlink prep in the sewer compartment.
Coach Control: Spyder Multiplex and Vegatouch
Coach systems run through the Spyder Controls Multiplex System with the Firefly Integrations Mira Module. A centralized 7-inch main monitor pairs with an interior entryway Spyder switch panel and additional Spyder panels through the coach. The Vegatouch app adds Bluetooth-range smartphone control of the generator, lighting, climate, and water pump.
Exterior Build
The exterior runs full-body paint with three layers of clear coat (four colors offered), a side-mounted powered patio awning with LED lighting, slide-out toppers, side-swinging exterior storage doors with gas shocks, frameless single-pane windows, chrome power heated side-view mirrors with integrated cameras, and an automatic double entry step. An exterior TV with soundbar is optional.
Interior, Kitchen, and Bath
The interior runs handcrafted overhead cabinetry, dimmable LED lighting, soft-close drawers, solar and privacy shades, a soft-touch vinyl ceiling, and prep for washer and dryer. Two interior décor packages are offered with coordinated upholstery, cabinetry, and flooring.
The galley runs an 18-cubic-foot stainless-steel residential refrigerator with bottom freezer, a 1.5-cubic-foot smart convection microwave, a large sink with pull-down sprayer, a full tile backsplash, and a three-burner LP cooktop (optional oven range upgrade). An optional stacked washer/dryer and central vacuum system are available. The 38 CL also offers an optional standalone living-area fireplace.
The Two-Full-Bathroom 38 BL Differentiator
Bathroom configuration is one of the Byway's most distinctive features, and each plan takes a different approach.
The 33 FL runs a single full bathroom with a 28.5-by-40.5-inch shower and a gravity flush toilet.
The 38 BL steps up to two full bathrooms (not a bath-and-a-half). The main bath has a 28.5-by-40.5-inch shower with a gravity flush toilet, and the rear bath adds a 34.5-by-34.5-inch shower with a macerator toilet. Two-full-bathroom Class A diesel pushers are unusual at this price tier, which is a real differentiator for families and buyers who host guests.
The 38 CL runs a bath-and-a-half with a 28.5-by-40.5-inch main shower, a gravity flush toilet in the main bath, and a macerator toilet in the half-bath.
Master Bedroom and Sleeping
Every Byway floor plan carries a 72-by-80-inch King mattress in the master with a handcrafted privacy door, LED reading lights, nightstands, a mounted bedroom TV, overhead cabinets with headboard, and a wardrobe with drawers underneath.
The 38 BL adds dedicated rear passenger-side bunk beds (28-by-70-inch) for family travel. An optional electric front overhead drop-down cab bunk (72-by-30-inch, rated for 250 lb) is available across every plan for guest capacity.

Tiffin Byway FAQs
What is the Tiffin Byway?
The Tiffin Byway is a Class A diesel pusher built by Tiffin Motorhomes on the Freightliner XCS straight-rail rear-engine chassis with a standard Cummins B6.7 340HP diesel. The Byway is the most accessible Class A diesel pusher in the Tiffin lineup, sitting below the entry-tier Allegro Red, the mid-tier Phaeton, and the flagship Allegro Bus. It's aimed at first-time diesel pusher buyers, families, and travelers who want diesel pusher credentials at a more accessible price point.
What engine and chassis are on the Tiffin Byway?
Every Byway comes standard with the Cummins B6.7 340HP diesel (700 lb-ft of torque), paired with the Allison 2500 MH 6-speed automatic transmission on the Freightliner XCS straight-rail rear-engine chassis. Standard chassis equipment includes a full air brake system, VGT engine brake, Freightliner VFS air-ride front suspension, V-Series V-Ride rear suspension, custom-tuned Sachs shocks, hydraulic leveling jacks, automatic traction control, and tire pressure monitoring. The Cummins B6.7 is one of the most serviceable diesel engines in the RV industry with strong dealer service network coverage.
How much can the Tiffin Byway tow?
Every Byway has a 5,000-pound hitch rating (with a 3,200-pound maximum trailer weight at GVWR), regardless of floor plan. The 29,800-lb GVWR and 33,000-lb GCWR put the Byway in the lighter-duty diesel pusher category, sized for a small toad vehicle, utility trailer, or other light load rather than the heavier towing capability of a tag-axle coach.
What floor plans does the Tiffin Byway come in?
The Byway is available at MHSRV in three floor plans: the 33 FL (35 ft 2 in, ~330 sq ft, four slides, sleeps 3-5, single full bath, the compact couples-focused plan with a standard 95-inch Super Sofa), the 38 BL (39 ft 6 in, ~385 sq ft, three slides, sleeps 4-7, two full bathrooms, dedicated rear passenger-side bunk beds, the family-friendly bunk plan), and the 38 CL (39 ft 6 in, ~395 sq ft, three slides, sleeps 2-5, bath-and-a-half, 68-inch theater seating, optional standalone fireplace, the most spacious couples-focused plan).
Does the Tiffin Byway have two full bathrooms?
Yes, on the 38 BL floor plan. The Tiffin Byway 38 BL runs two full bathrooms (not a bath-and-a-half), one of the more unusual configurations in the Class A diesel pusher segment. The main bath has a 28.5-by-40.5-inch one-piece molded fiberglass shower with a gravity flush toilet, and the rear bath adds a 34.5-by-34.5-inch shower with a macerator toilet. Two-full-bathroom Class A diesel pushers are unusual at this price tier, which makes the Byway 38 BL a strong differentiator for families, traveling groups, and full-time travelers who host guests. The 33 FL runs a single full bathroom, and the 38 CL runs a bath-and-a-half.
What is the difference between the Byway 38 BL and 38 CL?
The Byway 38 BL and 38 CL are both 39 ft 6 in floor plans on the same chassis but take different approaches to interior layout. The 38 BL is the family-friendly bunk plan with two full bathrooms, dedicated rear passenger-side bunk beds, and a 68-inch air-coil sofa bed, sleeping up to seven. The 38 CL is the couples-focused luxury plan with a bath-and-a-half layout, standard 68-inch theater seating, a 72-inch booth dinette-sleeper, an optional standalone fireplace, and the largest interior square footage in the lineup at about 395 sq ft (vs about 385 sq ft on the 38 BL). Pick the 38 BL for family travel with kids or guests. Pick the 38 CL for couples travel with maximum interior space and luxury interior content.
Does the Tiffin Byway come in a bunk model floor plan?
Yes. The Byway 38 BL is the family-friendly bunk model in the lineup, with dedicated rear passenger-side bunk beds (28-by-70-inch). Combined with the standard 68-inch air-coil sofa bed and the optional electric front overhead drop-down cab bunk (rated for 250 pounds), the 38 BL sleeps up to seven. Bunk-model Class A diesel pushers are relatively rare in the segment, especially at this price point.
How does the Tiffin Byway handle off-grid camping?
Every Byway carries an 8-kW Onan Quiet Diesel generator on a slide tray, a 2,000-watt pure sine wave inverter/charger with auto-gen start, and four 6-volt 225 Ah flooded lead-acid house batteries as standard. Solar prep with auxiliary docking ports is also standard, plus an auxiliary solar port for portable panels. Tiffin doesn't currently offer a factory rooftop solar package on the Byway, but the prep lets buyers easily add aftermarket panels post-purchase. Optional connectivity upgrades include an in-motion satellite dish, a Wi-Fi booster, and Starlink prep in the sewer compartment.
What is the bedroom like in the Tiffin Byway?
Every Byway floor plan carries a 72-by-80-inch King mattress in the master bedroom with a handcrafted privacy door, LED reading lights, nightstands with hardwood-finished tops, a mounted bedroom TV, overhead cabinets with headboard, and a wardrobe with drawers underneath. The 38 BL adds dedicated rear passenger-side bunk beds for family travel. An optional electric front overhead drop-down cab bunk is available across every plan for extra guest capacity.
What is the difference between the Byway and the Allegro Red?
The Byway and the Tiffin Allegro Red are both Class A diesel pushers in the Tiffin lineup, but they sit at different tiers. The Byway is built on the Freightliner XCS chassis with the Cummins B6.7 340HP diesel and Allison 2500 MH transmission (vs Freightliner XCR with Cummins L9 380HP and Allison 3000 MH on the Allegro Red). The Byway has a 29,800-lb GVWR and 5,000-lb hitch (vs 38,320-lb GVWR and 10,000-lb hitch on the Allegro Red) and offers only the LP coach configuration (vs the Allegro Red's standard LP plus optional Hydronic/All-Electric). Pick the Byway for the more accessible entry into Tiffin diesel pusher ownership and the 38 BL two-full-bathroom family plan. Pick the Allegro Red for the heavier chassis, larger diesel, higher tow rating, and the optional all-electric configuration.
Do I need a CDL to drive a Tiffin Byway?
In most states, no CDL is required to operate a Tiffin Byway because it is a personal-use recreational vehicle. That said, CDL and non-commercial license requirements vary by state, particularly for motorhomes above certain weight or length thresholds. The 29,800-lb GVWR Byway is under most state CDL triggers, but buyers should check with their state's DMV before purchase.
