The 2018 Tiffin Phaeton 40IH is a premium Class A diesel motorhome designed for travelers who refuse to compromise on luxury or storage. Built on Tiffin’s proprietary Powerglide chassis, this model is celebrated for its "flat-floor" design, which eliminates the step up into the bedroom and significantly expands the exterior basement storage capacity.

Performance & Chassis

• Engine: Driven by a Cummins L9 450 HP diesel engine providing 1,250 lb-ft of torque for confident mountain climbing and highway merging.
• Transmission: Equipped with the reliable Allison 3000 MH 6-speed automatic transmission.
• Capability: A heavy-duty 10,000 lb hitch allows for easy towing of a full-size vehicle or a stacker trailer.
• Ride Quality: The Powerglide raised-rail chassis offers an independent front suspension for a smoother, automotive-style driving experience.

Interior Living & Layout

The 40IH is a "bath-and-a-half" floor plan, making it ideal for hosting guests while maintaining owner privacy.

• Gourmet Kitchen: Features solid-surface countertops, a residential-sized refrigerator, an induction cooktop, and an optional drawer-style dishwasher.
• Spacious Lounge: The living area utilizes four slide-outs to create a wide-open floor plan, often featuring a televator TV and ultra-leather seating options like theater recliners or an expandable sofa.
• Master Suite: Includes a standard King-size bed with a memory foam mattress and a dedicated entertainment center.
• Dual Bathrooms: A mid-coach half-bath serves guests, while the massive rear master bath features dual vanities, a large residential-style shower, and a stacked washer/dryer.

Premium Amenities

• Climate Control: The Aqua-Hot hydronic heating system provides quiet, engine-independent heat and "endless" hot water.
• Year-Round Comfort: Includes heated tile floors throughout and three 15,000 BTU low-profile roof air conditioners.
• Power Management: A 10.0 kW Onan diesel generator on a slide-out tray ensures you have plenty of power while dry camping.
• Entertainment: An exterior TV and soundbar allow for outdoor movie nights under the massive electric patio awnings.

Core Specifications
