2009 Monaco RV Dynasty YORKSHIRE IV

2009 Monaco Dynasty® Yorkshire IV 45' Quad Slide • Bath & Half • Cummins ISM 500HP Pre-DEF • Allison 4000 6-Speed • Tag Axle

The Monaco Dynasty® sits near the top of Monaco's entire lineup — and the Yorkshire IV is among the most livable floorplans they ever built. At 45 feet with four full slides, this coach opens into a true residential layout, with living room, galley, and bedroom each occupying their own clearly defined zones. Natural Cherry cabinetry runs throughout, warmed by an Aqua-Hot® 600D hydronic system and backed by a meaningful list of recent upgrades — three brand new roof A/C units, new living room furniture and carpeting, new chassis and house batteries, and a professionally applied silicone roof coating. The 500 HP Cummins ISM is pre-DEF, meaning none of the emissions system complexity that follows post-2010 diesels, and the coach is fully set up for flat towing with a Blue Ox tow bar and Air Force One supplemental braking. Interior condition is very good throughout, with no accidents on record. A serious, well-equipped luxury coach for full-timers and extended travelers who want proven performance without ongoing emissions headaches.

CHASSIS, POWER & DRIVING CONFIDENCE

• Cummins® ISM 500 HP Pre-DEF Engine – The ISM's 11.0L displaces 1,550 lb-ft of torque at 1,300 RPM, and running pre-DEF means no diesel exhaust fluid system, no DPF filter, and no regeneration cycles — a significant long-term ownership advantage over post-2010 emissions-equipped diesels.
• Allison® 4000 MH 6-Speed Transmission – The heavy-duty 4000 series is purpose-matched to the ISM 500's output, delivering smooth, confident power transfer that the lighter 3000 MH is not rated to handle.
• Roadmaster® S-Series Semi-Monocoque Chassis – Monaco's flagship chassis platform distributes stress evenly through the entire structure using a trussed superstructure design, reducing torque flex and extending the structural lifespan of the coach.
• Tag Axle – Provides additional rear load capacity and improved rear stability at highway speed; lifts with a push of a button for tight-quarter maneuvering in campgrounds.
• Steer Safe Steering Stabilizers – Installed to reduce steering wander and enhance directional control, providing an added layer of safety and driver confidence on long highway stretches.
• Cushion Air Glide Suspension – Ten shocks and ten air bags, eight outboard-mounted, with automatic air leveling for a consistently level coach on uneven terrain.
• Two-Stage Jacobs Engine Brake – Provides aggressive, controllable downhill deceleration without overloading the service brakes on long grades.
• Front & Rear Disc Brakes – The ISM 500-equipped Dynasty runs four-wheel disc brakes, a meaningful safety upgrade over the rear-drum setup on ISL 425 models.

EXTERIOR HIGHLIGHTS & STORAGE

• Talin Stainless Steel Guardian Plates – Low-profile stainless plates protect the lower exterior panels from road debris, gravel strikes, and curb contact — practical protection that keeps the finish intact over highway miles.
• Two Bay Power Slide Trays – Bay-mounted slide-out trays pull fully clear of the storage compartment, accessible from either side of the coach, so gear is always within easy reach without bending or reaching deep.
• Silicone Roof Coating by SW Florida RV – Professional silicone coating applied to the roof membrane for superior UV protection, water resistance, and long-term roofing integrity.
• Sunscreens for Exterior Windows and Tires – UV-protection covers for both windows and tires, particularly valuable for warm-climate storage.
• Winegard Trav'ler® Automated Satellite System – Roof-mounted automated satellite dish deploys and acquires DirecTV signal automatically — no manual aiming required, no separate dish to set up at camp.
• Blue Ox Tow Bar & Air Force One Braking System – Complete flat-tow setup ready to go. Air Force One provides proportional supplemental braking on the dinghy vehicle — required in many states and essential for safe towing at this weight class.

COCKPIT & CAMERA SYSTEMS

• Wireless Backup Camera System with Sideview Mirror Camera Display – Rear backup camera feeds to the dash display, with additional camera images from both sideview mirrors also visible from the cockpit — providing comprehensive visibility on all sides while maneuvering.
• Rand McNally GPS Navigation System – Updated GPS navigation unit replaces the factory system for current maps and routing.
• Power Cord Reel – Automated retractable shore power cord reel for clean, tangle-free hookup and stowage.

INTERIOR LIVING & ENTERTAINING

• 45' Yorkshire IV Quad Slide Floorplan – Four full slides transform the coach interior into a layout that rivals a residential apartment in usable square footage, with cockpit, living room, galley, and master bedroom each opening independently.
• Natural Cherry Cabinetry – Warm, premium Natural Cherry wood throughout ties the interior together and sets a high baseline for the coach's residential feel.
• New Living Room Furniture & New Carpeting – Updated living room furniture and new carpet throughout give the interior a fresh, move-in-ready presentation.
• Newer Cockpit Furniture – Updated pilot and co-pilot seating for fresh comfort behind the wheel.
• Power Interior Blackout Shades for All Windows – Power-operated interior blackout shades throughout the coach provide complete light control and privacy at the touch of a button.
• Central Vacuum System – Built-in central vacuum keeps the interior clean without hauling a portable unit aboard.

KITCHEN & APPLIANCES

• Maytag Washer & Dryer — Full Separate Units – A dedicated Maytag washer and separate dryer for genuine residential laundry capacity. A practical advantage over typical RV combination machines.
• Full-Size Residential Refrigerator with Ice Maker – Full-size coach refrigerator delivers residential storage capacity for extended travel without rationing.
• Newer Microwave – Updated microwave keeps the galley current and functional.
• Amana Range – Built-in range for full cooking capability.
• High-Gloss Solid Surface Countertops – Throughout galley and bath for durable, low-maintenance surfaces.

BEDROOM & BATH COMFORT

• Sleep Number® Bed – Dual Controls – Each side of the bed adjusts independently, so both occupants dial in their preferred firmness level without compromise.
• Bath & Half Layout – Full private bath in the rear plus a half bath mid-coach — guests never walk through the bedroom to reach a facility. New flooring installed in the half bath following a water intrusion repair that has since been resolved.

ENTERTAINMENT & CONNECTIVITY

• Newer Samsung TVs & Sound Bar – Updated flat screens throughout with a sound bar in the living area for improved audio quality.
• Sirius Satellite Radio – Built-in Sirius tuner for nationwide music and programming.
• Bluetooth® HandsFreeLink® – Integrated Bluetooth for hands-free phone calls from the cockpit.

MECHANICAL & UTILITY SYSTEMS

• Aqua-Hot® 600D Hydronic Heating System – Diesel-fired hydronic system heats the coach and provides effectively unlimited domestic hot water — no electric tank to drain, and heat is available without shore power.
• Onan® 10kW Generator – 2,236 Hours – Full-power generator on a slide-out service tray providing complete electrical independence. The generator was operated during all driving for climate control, accounting for the accumulated hours.
• 3 Brand New Roof A/C Units – All three roof-mounted air conditioners have been replaced — cooling is operating at full efficiency with no deferred maintenance on the highest-demand system in a warm-climate coach.
• Chassis Batteries Replaced February 2021 – Three chassis batteries in excellent condition.
• House Batteries Replaced August 2022 – Eight house batteries, maintenance-free AGM, replaced August 2022.
• Magnum® 2,000W Pure Sine Wave Inverter – Clean inverter output for sensitive electronics without generator noise.
• Surge Guard™ Automatic Transfer Switch – Protects all coach electronics from shore power fluctuations and automatically manages power source transitions.

The Monaco Dynasty® Yorkshire IV is a compelling package at any price — 45 feet of four-slide floorplan, a 500 HP pre-DEF drivetrain, hydronic heat, new A/C units, new interior furniture and flooring, and a clean accident-free history. For the buyer looking for proven luxury without ongoing emissions complexity, this Dynasty is ready to travel.
