2026 40 IH Features and Options

The 2026 Tiffin Motorhomes Phaeton 40 IH delivers luxury, performance, and residential comfort in a premium Class A diesel motorhome built for long-distance touring or full-time living. Built on Tiffin’s PowerGlide® XC raised-rail chassis with a powerful 450-horsepower Cummins® diesel engine, this coach combines smooth highway performance with the stability and reliability serious travelers expect.

At approximately 41' 4" long, the 40 IH strikes an excellent balance between spacious living and manageable drivability, making it ideal for couples or families who want premium amenities without oversize handling.


Spacious, Residential Living

Step inside and you’ll appreciate how the quad slide-outs open the interior into a bright, expansive space perfect for relaxing or entertaining. Premium finishes, panoramic windows, and thoughtful design create a true home-on-wheels atmosphere.

The living area flows seamlessly into the residential kitchen, where solid-surface countertops, abundant storage, and quality appliances make meal preparation a pleasure on the road.


Bath-and-a-Half Comfort

One of the standout features of the 40 IH is its bath-and-a-half layout, offering added convenience whether you’re on the road or at the campground. This layout enhances privacy and functionality, especially during longer trips.

The rear master suite provides a restful retreat with ample wardrobe space and storage, making every night on the road feel like home.


Built for Long-Distance Travel

Engineered for performance and comfort, the Phaeton 40 IH includes advanced driver-assist technologies such as adaptive cruise control and collision mitigation to help make highway miles easier and safer. A powerful Onan® Quiet Diesel generator and generous tank capacities support off-grid stays and extended camping trips.
