2005 MONACO DYNASTY PLATINUM IV

2005 Monaco Dynasty Platinum IV – 400 HP Cummins ISL • Tag Axle • Four Slides • Up to 20,100 lb Towing Capacity

The 2005 Monaco Dynasty Platinum IV represents the peak of luxury and performance in a 40-foot Class A diesel pusher. Built on Monaco’s legendary Roadmaster S-Series tag-axle chassis and powered by the 400 HP Cummins ISL 8.9L turbo-diesel paired with an Allison 3000MH 6-speed transmission, this coach delivers commanding power and a remarkably smooth highway ride.

At 40' 10? overall length with four slide-outs, it provides the spacious interior of a much larger coach while maintaining excellent drivability and balance. Its up to 20,100 lb towing capacity means it can confidently handle heavy trailers, vehicles, or stacker setups—ideal for those traveling with toys or race rigs.

Inside, you’ll find the craftsmanship Monaco is known for: hand-finished hardwood cabinetry, solid-surface counters, ceramic tile flooring, plush UltraLeather seating, and a luxurious rear master suite featuring a full wardrobe and washer/dryer combo.

Every system has been professionally inspected and serviced—ready for immediate travel.
