2023 Newmar Essex 4551: A Quick Look
This 2023 Newmar Essex 4551, a pre-owned Class A motorhome, offers a sophisticated aesthetic and robust engineering. Positioned as Newmar’s second-highest line, it delivers many amenities found in the top-tier King Air but with a distinct, more traditional design palette. The specific unit features a soothing, muted color scheme throughout the interior.
Chassis & Construction
The Essex 4551 is built on the Spartan K3 chassis, powered by a 605 HP Cummins engine, noted as among the largest horsepower available in an RV. This contributes to a stable ride, enhanced by an air leveling system that complements traditional hydraulic leveling jacks. The coach also features superior insulation, evident in its quiet interior even near busy interstates.
Interior Living Spaces
Front Salon & Dining
The front living area includes a jackknife sleeper sofa, positioned below a lift-away TV, and electric theater seats with integrated storage. The booth dinette is designed for practicality, retracting significantly to allow more pass-through space when the slides are in for travel. The dining table adjusts in and out, and up and down, making it suitable as a standing or seated workstation. All seating surfaces feature soft, supple leather upholstery.
An included Samsung tablet provides comprehensive control over coach functions, including blinds, awnings, heating, and cooling, from any location inside or outside the RV.
Climate Control & Utilities
Heating and hot water are managed by an Oasis Chinook dual-loop system, which serves as both a continuous hot water heater and the furnace. The coach features three independent 15,000 BTU air conditioning units, each with integrated heat pumps. Three-zone heated floors extend even into the slide-out areas, providing consistent warmth.
Kitchen
The kitchen is equipped as a 100% electric coach with no propane. It features a Bosch convection microwave, a three-burner induction cooktop (a larger configuration than some other models), and a full-size residential Bosch refrigerator freezer with an in-door ice and water dispenser, a feature not common in motorhomes. Cabinets are lined with felt carpet to reduce noise and movement, and drawers are solid wood, full-extension, and soft-closing. A countertop extension provides additional workspace, and a dishwasher is integrated below the counter. The pantry features adjustable, full-extension shelves with an automatic locking bar for travel.
Mid-Half Bath
The half bath is designed with a sleek, pivot door that tucks away to maximize hallway space when slides are closed. It includes a macerating toilet, a small sink, and an integrated central vacuum system with both a traditional hose port and a sweep plate. A medicine cabinet with integrated 110V outlets and a window with a screen offer convenience and ventilation.
Master Suite & Rear Bath
The master bedroom’s accessibility is tighter with the slides in, as the bed nearly touches the dresser, which is common with a bath-and-a-half floor plan. The master bathroom features a large shower with bronze accents, a teak fold-away seat, and the Aqua View system, which recirculates cold water until it reaches the desired temperature, conserving fresh water. Both the master and half baths include macerating toilets. A unique emergency exit door in the master suite provides a low-to-the-ground egress point.
Driving & Cockpit Features
The cockpit features heated, cooled, and massaging power seats with lumbar support and footrests, all of which swivel to become part of the living area when parked. Newmar’s Comfort Drive steering system helps keep the coach centered on the road and allows for adjustable steering tightness based on driving conditions. Adjustable pedals, tilt and telescope steering, and memory settings for both steering wheel and seats enhance driver comfort and convenience.
Driver assistance technologies include a mobile eye system for collision warning and an integrated Curt Spectrum brake controller for towing. The dash hosts a comprehensive camera system with 360-degree views, side cameras, and three different towing views. A dash-mounted fan provides additional heating for the front area, separate from the chassis heat.
Exterior & Utility Bays
The exterior utility bays are designed for efficiency. The water bay features an exterior shower, a whole-house water filter, and a Manabloc system that allows isolation of water lines to specific areas for leak management. It also includes a power retractable water reel, traditional dump capabilities, and rinses for both black and gray tanks.
The coach is equipped with two 3000-watt inverters and two Lithionics batteries, with room for more. This power system allows the air conditioning units to operate while driving without needing to run the generator. A 50-foot 50-amp power cord is on a power rewind reel. The Oasis Chinook system, a clean-burning tankless hot water heater, is easily accessible for service. A large Cummins Onan Quiet Diesel generator is mounted on a slide-out for simplified maintenance access. All wiring throughout the coach is clearly marked, which can significantly reduce diagnostic time and costs during servicing.
The Bottom Line
The 2023 Newmar Essex 4551 stands out for its powerful chassis, comprehensive and integrated power system (allowing AC operation without generator while driving), and sophisticated water management. Its traditional interior design, high level of build quality, and driver-centric features like Comfort Drive steering and an integrated brake controller present a compelling combination for those seeking a high-capability, comfortable, and well-appointed motorhome.
