THE BEST QUALITY CLASS
MOTORHOME CONSTRUCTION

The unparalleled quality of Monaco Coach is built by design. Underneath each sleek exterior are copious amounts of refined workmanship. State-of-the-art innovation and manufacturing procedures are carefully chosen and utilized to give each Monaco motor coach the attention and support it deserves for every long road ahead.

Monaco Roadmaster Chassis

A CUSTOM FREIGHTLINER MOTORHOME CHASSIS

THE ROADMASTER CHASSIS®

A meticulously designed motorhome should be supported by an equally exceptional foundation. For that reason, Monaco Coach partnered with Freightliner Custom Chassis, a Daimler company and the parent company to Mercedes-Benz, to build on one of its newest Roadmaster chassis — the B-series, a durable modular bridge design featuring e-coated steel with protective undercoating. Command the road with a big-bore Cummins engine, and enjoy the smooth ride of an automatic four-point dual (hydraulic) leveling system for complete control. After all, you’re the one driving things.

UNSURPASSED STRENGTH

I-BEAM CONSTRUCTION

The Roadmaster chassis’ bridge features high-strength steel I-beams, accompanied by enhanced cross-sections that reduce unnecessary weight. Backed by rigorous road tests, you won’t find a stronger foundation.

HUCK BOLTS

Monaco Coach’s Roadmaster chassis features resilient huck bolt assembly. These bolts, known for their undeniable strength and vibration resistance, are considered the most reliable aerospace-grade fasteners available. Huck bolts have a longer fatigue life (up to 20%).

SIGNATURE E-COATED CHASSIS BRIDGE

Chassis components are e-coated, an electrically charged process that gives the steel bridge structure a long-lasting corrosion barrier. Moreover, the e-coat was put to one of the most rigorous trials, a 1,000-hour salt spray test to ensure your foundation holds up to the elements.

RIDE AND HANDLING FEATURES

ZF INDEPENDENT FRONT AIR SUSPENSION

Be in control with a Roadmaster chassis. The ZF independent front air suspension system helps prevent vehicle rollover, while dual wishbone-shaped arms minimize roll or sway and allow for a 60-degree wheel radius, which makes navigating tight spaces a breeze.

ULTRASTEER TAG AXLE

Exclusive to Freightliner, the Roadmaster chassis features an UltraSteer tag axle for precise maneuvering. Following the ideal turning path of the front suspension, this tag axle provides up to 17% reduction in curb-to-curb turning radius — a 140% improvement over other designs.

ULTRASTEER B-SERIES

The UltraSteer B-Series straight-beam axle and wide-track suspension arms provide increased lateral stiffness on models like Monaco Diplomat. Forward-mounted tie rods eliminate inside wheel tire scrub for accurate steering, even during sudden maneuvers.

V-RIDE REAR SUSPENSION

Experience power without limits. The Roadmaster chassis’ V-Ride rear suspension is the first-ever single-axle suspension rated at 24,000 pounds, meaning you can carry more gear without sacrificing ease or safety. Monaco Diplomat also features a 15,000-lb. integrated Class V hitch.

PREMIUM SACHS SHOCKS

Your motor coach rides with royalty. Not only does your motorhome need a solid foundation, it needs components to protect everything riding on it. Custom-tuned SACHS shocks, a part of the Rolls-Royce Co., dampen the rigors of the road to protect your coach.

MICHELIN TIRES, ALUMINUM WHEELS AND BENDIX® DISC BRAKES

Monaco Coach delivers stopping power with Bendix disc brakes for reduced fade and brake noise. And to make head turns, ride on the reliability of Michelin tires, paired with aluminum wheels to make your coach king of the road.

OTHER CHASSIS CONVENIENCES

POWER GENERATOR SLIDE

Want even more convenience? The lower fiberglass front fascia opens at the push of a button, providing easy access to the front chassis components, as well as the powerful Cummins Onan generator. If you’re the king of the road, you should hardly have to lift a finger.

DUAL-SIDE FUEL FILLS

Boundaries are just a suggestion with Monaco Coach. The Roadmaster chassis’ high-flow, 150-gal. fuel tanks allow you to go farther, fill up less often and fuel up on both sides of the coach. This diesel pusher is anything but ordinary.

ALL-WEATHER INCLUSIONS

Winter shouldn’t have to slow your travels down. The Roadmaster chassis provides every coach with a 1,500-watt block heater and automatic traction control, making even the toughest weather conditions feel less like a burden and more like a perk.



REVVED UP FOR ADVENTURE — CUMMINS MOTORHOME ENGINES


 

Legacies begin with power. Monaco Coach combines its custom Roadmaster chassis with select model Cummins motorhome engines. Cummins, the workhorse of the Class A diesel motor coach industry, has long been the favorite among motorhome owners for its fuel economy, renowned dependability and best-in-class power. Get ready to conquer mountains, even with your tow vehicle. With the Cummins name and Monaco Coach’s legacy of excellence, Mother Nature will be rolling out the red carpet.

CUMMINS ISL9 450 HP ENGINE

The Cummins ISL9 powers the Monaco Diplomat, delivering 450 HP with 1,250 lb.-ft. of peak torque. The ISL9 has the highest power-to-weight ratio for strong towing capacity and features two-stage engine brakes, a 160-amp Delco-Remy alternator and an Allison 3000 MH 6-speed transmission with electronic shifter.

COMPLETING THE DREAM WITH SOME COLOR

No Monaco Coach is complete without adding a touch of brilliance — in this case, your choice of paint. Each of our motorhomes come in distinct color palettes. Monaco Coach features its very own custom paint facility at its manufacturing location in Decatur, Indiana. Every coach makes its way through the 125,000-square-foot facility, visiting six different downdraft paint booth stations to achieve an automotive full-body paint with sand and buff high-gloss finish.
