Kenworth W900 Motorhome : The legendary Kenworth W900 is entering a new era as custom builders transform the iconic long-nose truck into one of the most extravagant motorhomes on the road. Known for its unmistakable design and heavy-duty durability, the W900 platform is now being adapted into a luxury “house on wheels” designed for long-distance travel and full-time living.
This motorhome concept blends the rugged strength of a Class-8 truck with the comfort of a premium RV. With advanced technology, massive living space, and powerful diesel performance, the W900 motorhome is attracting attention from travelers who want both reliability and luxury on cross-country journeys.
Rather than traditional recreational vehicles, these conversions prioritize durability, extended range, and residential-level comfort—making them ideal for extended travel across highways and remote destinations.
Exterior Design and Road Presence
Classic Truck Style Meets Modern RV Engineering
The W900 motorhome keeps the truck’s signature long hood and bold chrome grille, giving it a commanding presence on the road. Custom aerodynamic fairings and LED lighting upgrades modernize the exterior while improving visibility during long night drives.
Heavy-duty bumpers, reinforced body panels, and large exterior storage compartments make the vehicle capable of carrying outdoor gear such as bikes, kayaks, or small recreational vehicles.
Slide-out sections expand the living area when parked, transforming the motorhome from a highway hauler into a spacious mobile residence. Dual rear axles help maintain stability and improve weight distribution for long-distance travel.

Powertrain and Long-Distance Performance
Diesel Power Built for Heavy Loads
Under the hood, the motorhome typically uses a high-output diesel engine such as the Cummins X15. Built for commercial trucking, this powertrain delivers impressive torque and durability for hauling large motorhome conversions over long distances.
The engine pairs with an automated manual transmission designed for smooth shifting and reduced driver fatigue during extended highway drives.
Performance Overview
| Specification | Details |
|---|---|
| Engine | Cummins X15 turbo-diesel |
| Power Output | Up to 565 horsepower |
| Torque | Up to 1,850 lb-ft |
| Transmission | Automated manual gearbox |
| Estimated Range | Over 1,000 miles with large fuel tanks |
Air-ride suspension improves ride comfort, smoothing out rough highways and helping the massive vehicle remain stable during long road trips or mountain driving.
Driver Cabin and Technology
Modern Truck Cockpit with Advanced Safety
The driver area blends heavy-duty trucking functionality with modern comfort features. Leather seating, a digital instrument cluster, and touchscreen controls give the cockpit a premium feel while keeping essential information easily accessible.
Driver-assistance technology helps manage the size of the vehicle during travel. Features such as adaptive cruise control, lane monitoring, blind-spot cameras, and forward collision alerts enhance safety on long drives.
Surround-view camera systems assist with parking and maneuvering in tight campgrounds or fuel stations.
Interior Living Space
A Mobile Luxury Apartment
Behind the cab, the motorhome transforms into a full residential living space. Custom conversions often include a private bedroom, full kitchen, lounge area, and a spacious bathroom.
A typical layout features a king-size bed in the rear suite, premium cabinetry, and modern appliances including induction cooktops and residential refrigerators. Comfortable lounge seating and large entertainment screens create a relaxing space for evenings on the road.
Interior Amenities
| Area | Features |
|---|---|
| Bedroom | King bed and storage cabinetry |
| Kitchen | Induction cooktop and full refrigerator |
| Lounge | Leather sofas and large TV |
| Bathroom | Full shower and modern fixtures |
| Connectivity | Satellite internet and smart controls |
Large water tanks, solar panels, and battery systems allow the motorhome to operate off-grid for extended periods.
Smart Technology and Connectivity
Modern motorhome conversions include centralized touchscreen systems that manage lighting, climate control, water levels, and electrical systems.
Wireless connectivity, satellite internet, and integrated navigation systems make it easier for travelers to stay connected and plan routes suitable for oversized vehicles.
Smart monitoring systems can also alert owners about battery levels, tank capacity, or maintenance needs.
Why the W900 Motorhome Stands Out
The transformation of the Kenworth W900 into a luxury motorhome highlights a growing trend in high-end RV travel. Instead of lightweight recreational vehicles, some travelers prefer heavy-duty truck platforms that offer greater durability, towing capability, and long-distance reliability.
With its combination of powerful diesel performance, spacious living areas, and advanced technology, the W900 motorhome delivers a unique blend of trucking heritage and luxury travel.
For drivers seeking a motorhome built for both endurance and comfort, this conversion represents one of the most distinctive ways to explore the open road.
