This 2003 Prevost Featherlite Vantare H3-45 is a premier diesel-pusher motorhome built on a commercial-grade Prevost coach chassis and finished by Featherlite (generally known for high-end, custom interiors). Combining robust bus-quality construction with luxurious living spaces, this coach remains a favorite among full-time RVers and custom conversion builders alike. Its 45-foot length provides spacious interiors, upscale amenities, and the ability to support substantial customization — making it ideal for those who want true “home on wheels” comfort with rugged dependability.

What Sets It Apart

Commercial-Grade Prevost Chassis

The H3-45 is based on a heavy-duty Prevost coach platform originally designed for long-distance passenger service, meaning its frame, suspension, engine, and drivetrain are built for longevity and rugged use. These features often translate to better ride quality, higher resale value, and more upgrade potential compared with conventional recreational vehicles.

Spacious, Custom Interiors

Featherlite Vantare conversions are known for high-end cabinetry, premium materials, generous living spaces, and thoughtful layouts. A typical H3-45 includes separate living and bedroom areas, large galley kitchens, multiple seating zones, and often upgraded entertainment systems — all contributing to a true residential experience on the road.

Strong Power & Performance

Many 2003 H3-45 coaches were equipped with Detroit Diesel Series?60 engines or equivalent heavy-duty powerplants paired with Allison automatic transmissions, giving them ample power for highway cruising and long-haul travel. The diesel engine’s torque and the coach’s robust chassis make it suitable for towing or extensive cross-country journeys.

Typical Feature Highlights

• Large Fuel Tank & Range: Extended-capacity fuel tanks (~200–250?gallons) for long range between fill-ups.
• Generator: Onboard diesel generator (often 17.5–20?kW) for reliable power when off-grid.
• Residential-Style Kitchen: Full-size refrigerator, convection/microwave oven, cooktop, and solid-surface countertops.
• Separate Bathroom & Bedroom: Dedicated bedroom area with wardrobe storage, washer/dryer hookups, and often full bath with spacious shower.
• Entertainment & Comfort: Built-in TV systems, premium sound, skylights, and high-end upholstery.
• Climate Control: Multiple roof air conditioners with heat pumps and efficient diesel furnaces improve comfort in different climates.

Why This Coach Still Appeals

• Unmatched Longevity: Prevost chassis and drivetrains routinely perform well beyond typical RV lifespans when properly maintained.
• Customization Potential: Many owners upgrade insulation, electronics, solar systems, interior finishes, or convert units to boutique motorhomes.
• Resale Value: Well-maintained H3-45 coaches tend to hold value well relative to typical Class?A motorhomes due to build quality and prestige.
• Spaciousness & Comfort: With multiple slide-outs and abundant interior square footage, these are some of the most livable motorhomes for extended travel or full-time living.
