Introduction
The 2026 Kenworth W1250 RV arrives at a time when the motorhome market is asking for far more than just a place to sleep on wheels. Travelers want the hauling muscle of a heavy‑duty truck combined with the refinement of a boutique hotel, and Kenworth has answered that call with the W1250. Built on the company’s proven W900 platform, this model pushes the envelope in terms of payload, towing capacity, and interior luxury. In the following pages we’ll walk through every major aspect of the vehicle, from the first glance at its rugged exterior to the quiet comfort of its night‑mode cabin, and finish with a look at pricing, availability, and the questions most buyers tend to ask.
Exterior Design
The silhouette of the W1250 is unmistakable. The long, straight‑line hood and the signature Kenworth grille sit behind a set of oversize 22‑inch off‑road tires that hint at the machine’s capability to tackle everything from interstate highways to remote desert tracks. The bodywork is a blend of high‑strength steel and aluminum panels that keep weight down without compromising durability.
Key exterior features include:
- A reinforced chassis that can support a gross vehicle weight rating (GVWR) of over 30,000 lb.
- An aerodynamic “RV module” that tapers toward the rear, reducing drag while preserving interior volume.
- Full‑LED headlamps with adaptive lighting, plus a strip of auxiliary driving lights flanking the lower grille.
- Front tow hooks and skid plates engineered to absorb impacts when navigating rough terrain.
- Roof‑mounted racks and a climb‑assist ladder that give easy access to solar panels, water tanks, and adventure gear.
Optional paint finishes range from a high‑gloss “Midnight Black” to a two‑tone “Desert Sand” scheme, each accompanied by tasteful graphics that emphasize the blend of truck heritage and motorhome elegance.
Interior Layout
Step inside and the W1250 quickly discards any notion of a utilitarian camper. The cabin is divided into several distinct zones, each crafted with premium materials and a focus on ergonomics.
The sleeping area features a master berth that folds out from the rear wall, complete with a memory‑foam mattress and individual climate controls. Adjacent to it, a secondary “guest” platform can be configured as a set of twin bunks or a lounge that converts into a queen‑size bed.
The kitchen occupies the central aisle, boasting a stainless‑steel four‑burner induction cooktop, a 12‑inch convection oven, and a 120‑quart refrigerator that runs on both diesel and solar power. Cabinets are lined with soft‑close hinges, and a pull‑out pantry provides ample storage for dry goods.
A separate bathroom, positioned just behind the kitchen, includes a walk‑in shower with a low‑flow faucet, a composting toilet, and a vanity with a mirrored LED panel.
The living area offers two recliner chairs that swivel to face a 15‑inch entertainment screen mounted on the ceiling. Ambient LED lighting runs along the ceiling trim, letting occupants choose from a palette of warm and cool hues to suit the time of day or mood.
Powertrain Options
Kenworth gives owners a choice between two powerplants, each paired with a heavy‑duty 12‑speed automatic transmission.
-
Diesel‑only – A 15‑liter Cummins X15 engine, tuned for low‑end torque, delivers 625 hp and 2,050 lb‑ft of torque. The configuration excels at hauling trailers and tackling steep grades, while the integrated after‑treatment system keeps emissions within EPA limits.
-
Hybrid – A plug‑in hybrid system pairs a smaller 10‑liter turbo‑diesel with a 300 kW electric motor, offering a combined output of 720 hp and 2,200 lb‑ft of torque. The battery pack, mounted under the floor, can be recharged via the on‑board charger or through solar arrays mounted on the roof, providing up to 40 miles of electric‑only operation for quiet campground use.
Both powertrains share a common set of features: a robust cooling system, a torque‑vectoring differential, and a suite of driver‑assist sensors that manage engine load based on terrain and payload.
Driving Dynamics
With a vehicle of this size, smooth handling is often a concern, but the W1250’s suspension and chassis engineering mitigate most of the typical drawbacks.
An air‑suspension system automatically adjusts ride height and damping rates based on load and road conditions. When the vehicle is fully loaded, the system lowers the rear axle by up to two inches to improve stability, then raises it for off‑road excursions to increase ground clearance.
Power steering is calibrated to provide a light feel at low speeds, yet a firmer feedback when navigating winding mountain roads. Electronic stability control (ESC) works in conjunction with the anti‑lock braking system (ABS) to keep the vehicle planted, even when sudden evasive maneuvers are required.
The ride is surprisingly quiet; a layer of acoustic insulation combined with a vibration‑damping engine mount reduces cabin noise to levels comparable with a luxury sedan.
Technology Suite
The W1250 treats technology as a core component of the travel experience. A central 12‑inch touchscreen serves as the hub for vehicle diagnostics, climate control, and entertainment. From this screen you can:
- Monitor fuel consumption, transmission temperature, and hybrid battery state in real time.
- Adjust each zone’s temperature independently, with a “sleep mode” that reduces HVAC output during the night.
- Access a multi‑camera system that includes front, rear, and side views, all displayed in a picture‑in‑picture layout.
- Stream music and video via Wi‑Fi or a cellular hotspot, while a premium 12‑speaker surround system fills the cabin with clear audio.
The RV also supports remote diagnostics through a mobile app, allowing owners to receive alerts about maintenance needs, tire pressure changes, or low battery levels while they’re away from the vehicle.
Safety Features
Safety was clearly a top priority during the W1250’s development. In addition to the fundamental ESC and ABS systems, the vehicle offers:
- Adaptive cruise control that automatically adjusts speed based on traffic flow, with a stop‑and‑go function for urban environments.
- Lane‑keeping assist and lane‑departure warning that gently steer the vehicle back into its lane if it begins to drift.
- Forward collision warning coupled with automatic emergency braking, capable of detecting pedestrians and large animals.
- Tire pressure monitoring that not only alerts the driver but also inflates the tires via an integrated air‑supply when the vehicle is stationary.
- A 360‑degree camera suite that stitches together a bird’s‑eye view, simplifying low‑speed maneuvers in tight campgrounds.
Night vision is integrated into the front headlamps, projecting an infrared overlay on the display to illuminate the road ahead without blinding others.
Practicality for Long‑Term Travel
The W1250 is designed to be a home on wheels that can sustain a family or a small crew for weeks, even months, without resupply.
Freshwater storage totals 150 gallons, with a built-in filtration system that removes sediment and chlorine, delivering drinkable water on demand. Grey‑water is stored in a 100‑gallon tank that can be emptied at designated dump stations.
Solar panels mounted on the roof generate up to 5 kW of power, feeding the battery pack and auxiliary systems while the vehicle is parked. An optional generator provides additional backup in extreme climates.
Interior storage is modular; wall‑mounted cabinets can be reconfigured to hold surfboards, bicycles, or extra fuel drums. Fold‑out workstations emerge from underneath the kitchen counter, turning the RV into a mobile office when needed.
All service points—oil dipstick, filter housings, brake lines—are accessible from removable panels on the exterior, allowing routine maintenance without the need for a lift.
