Description
Offered for sale is this exceptionally well-cared-for, one-owner 2015 Newmar Essex 4503. This 45-foot luxury diesel pusher is powered by a Cummins ISX 600 HP engine on a Freightliner tag-axle chassis and has approximately 85,000 miles. Originally carrying an MSRP of nearly $760,000, this is a highly equipped luxury coach with an exceptional ownership, maintenance and storage history.
What truly sets this Essex apart is how it has been cared for. It was purchased new by the current owner and has never been used as a full-time residence. Throughout its life, it has been meticulously maintained, properly serviced and stored indoors in climate-controlled facilities whenever it was not traveling. The coach has spent its life primarily in the dry climates of Colorado and Arizona and has avoided the snow, road salt and prolonged humidity that many coaches of this age have experienced.
The owner is simply retiring from motorhome travel, creating an opportunity to purchase a coach that has received exceptional care throughout its life.
The 4503 floorplan features an impressive drivers-side full-wall slide along with two passenger-side slides-one in the living area and another in the bedroom. With all three slides extended, the interior provides the spacious residential feel expected from Newmar's Essex line.
Inside, beautiful Ginger Glaze high-gloss cherry cabinetry, an approximately $9,300 factory option, gives the coach a rich and timeless appearance. Tile flooring extends throughout the kitchen, bathroom, bedroom and living areas, complemented by electric in-floor heat. The floor heat remains operational in the bedroom and front portion of the coach; the kitchen and a portion of the living-area floor heat are currently inoperative.
Comfort systems include three 15,000-BTU Penguin central air conditioners with heat pumps and hydronic-zone diesel heat with continuous hot water. Auto Motion power window shades, including power windshield and driver/passenger shades, add convenience and privacy.
Electrical and coach systems include a 12.5 kW Onan diesel generator with just 309 hours, automatic generator start, a 2,800-watt pure-sine inverter, Silverleaf multiplex electrical system with multiple touchscreens, 50-amp service with power rewind cord reel, and a factory-installed six-panel Sunforce solar system.
The coach was originally equipped with both a dishwasher and washer/dryer. The dishwasher was removed and its space converted into a useful storage drawer, while the washer/dryer area was converted into a storage closet. The original plumbing remains in place, allowing a future owner to reinstall these appliances if desired.
Other notable equipment includes a Whirlpool stainless-steel 19.8-cu.-ft. residential refrigerator with icemaker and water dispenser, Advantium Speedcook microwave, all-electric induction cooking, central vacuum, Dometic exterior pullout freezer, power water-hose reel, exterior wash station, Sanicon system, remote-control rearview camera, side-view cameras, navigation, Sony surround sound, Winegard digital TV antenna, Bose bedroom audio, and multiple LED televisions.
Exterior and chassis features include Alcoa Dura-Brite aluminum wheels, air leveling, Comfort Drive steering, tire-pressure monitoring, hydraulic leveling jacks, power baggage-door locks, keyless entry, dual Girard Nova power patio awnings with wind sensors and LED lighting, Girard slideout covers and window awnings, frameless dual-pane tinted windows, and both a large storage tray and power sliding storage tray.
The condition of the interior reflects the way this coach has been used. It is non-smoking, has had no pets or children, and the kitchen has seen very little use. It was used exclusively for recreational travel rather than as a full-time home.
When not traveling, the coach has consistently been kept indoors in climate-controlled storage. Its travel history has been primarily throughout the Mountain West and western United States, including Colorado, Arizona, California and the Pacific Northwest. This careful storage and dry-climate history are particularly noteworthy for a 2015 coach.

This is not a coach being sold due to a known major mechanical problem or a history of deferred maintenance. The longtime owner has simply reached the point where he is retiring from motorhome travel.
The coach is currently located in northern Colorado and is available for inspection by serious prospective buyers. For someone looking for a Newmar Essex with one-owner history, exceptional storage conditions, extensive factory equipment and an unusually high level of care, this coach deserves a close look.
