Used 2025 Newmar King Aire 4521 Motor Home Class A - Diesel

The 4521 Floorplan — Designed for Space, Flow, and Privacy

The 4521 floorplan is widely regarded as one of the most livable and well-balanced layouts in the King Aire lineup, combining open-concept entertaining with true residential separation.

Key highlights of the 4521 layout include:

• Opposing living-room slide-outs, creating a wide, open main living area ideal for entertaining or extended stays

• Mid-ship half bath, providing guest access without compromising the private master suite

• Residential-style kitchen with expansive counter space and thoughtful appliance placement

• Dedicated dinette area with overhead cabinetry, balancing form and function

• Private rear master suite, fully separated from the living area

• Extended 84" bedroom slide, increasing bedroom floor space and walkability

• Lounge-style bedroom seating, replacing traditional furniture for a more refined, relaxed environment

• Large wardrobe and storage zones, consistent with full-time luxury travel expectations

The omission of a standard bedroom dresser and the use of custom structural framing further enhance openness and flow, reinforcing the 4521’s reputation as a true residential coach.

Custom Exterior Presence

The exterior reflects its one-off nature with special-order paint selections, custom awning fabric, and RGB LED ground lighting with controller, giving the coach a refined yet unmistakable presence after dark. Additional Newmar branding on the door-side awning reinforces its flagship identity without excess.

Refined Interior Craftsmanship

Inside, the coach is finished in Sedona Maple hardwood cabinetry, delivering a warm, tailored aesthetic more reminiscent of a private luxury residence than a recreational vehicle. Every material choice and layout decision supports comfort, longevity, and understated elegance.

Technology, Connectivity & Capability

This 2025 King Aire 4521 blends luxury with long-haul capability, making it equally suited for cross-country travel or extended destination living:

• Starlink internet system

• Four SunFree solar panels

• Enhanced A/V wiring retained for future flexibility

• Advanced security system

• Rear camera system with additional prep

• 30A / 120V trailer power integration

This is a coach engineered to function as both a luxury residence and a mobile command center.

Proven NASCAR Pedigree

What elevates this King Aire into true collector territory is its provenance. Originally owned by Legacy Motor Club, the coach features a door personally signed by Richard Petty, Jimmie Johnson, and John Hunter Nemechek—three names representing multiple generations of NASCAR excellence.

This isn’t memorabilia added later. It’s authentic history, permanently embedded into the coach itself.

This 2025 Newmar King Aire 4521 is more than rare. It’s intentional, storied, and impossible to replicate.
