2004 Monaco Beaver Marquis Amethyst


The Beaver Marquis has long been recognized as one of the most luxurious motor coaches ever built and often referred to as the “Crown Jewel” of the American highway! This was the last production year for the Marquis at the original Beaver production facility in Bend OR and marked the end of the “real” Marquis with its stunning wood cabinetry and striking interior elegance. After production was moved to the Monaco plant in Coburg OR in 2005, the Marquis lost much of its charm and heritage and before long the Beaver Marquis simply became another high end Monaco model.

In 2004 the Marquis was offered in a variety of floor plans and configurations starting with the 2 slide 40’ Jasper & Ruby models, followed by the 2 slide 42’ Amethyst with its mid entry option, then came the 2 slide 42’ Emerald followed by the 42’ 3 slide Garnet, the 42’ 4 slide Topaz and lastly the 45’ 3 slide Sapphire. This model is the 42’ 2 slide Amethyst with its unique and highly sought after mid entry configuration, please see floor plan below.

The Amethyst, as with the other Marquis models is constructed on the fabulous proprietary Roadmaster Magnum Series Chassis with its 10 large airbags set outboard of the chassis rails for stability and providing one of the most comfortable rides in the industry. The Bendix hydraulic over air disk brakes front and rear provide a great sense of security when you step on the brakes and will bring this majestic coach to a stop as though you were driving a much smaller vehicle. The coach is powered by a CAT C-12 engine producing 505-HP and a whopping 1,850 lbs-ft torque, its simply amazing how fast this coach will accelerate when needed or when climbing long mountain roads.

With only 34,000 carefully driven miles and two discerning owners this coach is in pristine condition inside and out. Always stored inside when not in use the full body paint is like new with no blemishes to be be found. The interior is simply stunning as you will see from the photos below, the combination of the narural maple cabinets with Mappa Burl Inlay door and drawer fronts, creamy ceramic tile floor, rich warm fabrics and halogen lighting all combine to create wonderful casual elegance! Enjoy your tour of this incredible coach, whether you are thinking of going full-time RV-ing or just weekend jaunts, we think you will agree this coach is simply an amazing home on wheels.

Storage Compartments
The storage compartments on the drivers side of the coach feature a large double door storage cabinet and a narrow pass through bay.
Aluminum Superstructure
Notice the aluminum superstructure used to frame the underbelly storage compartments.

Plumbing Bay
This is tha way a plumbing bay should be designed! First all the surfaces are lined in non corrosive stainless steel, second all the interior plumbing facilities have their own hot and cold water shut off valves, third rather than manual grey and black water pull valves these are electric simply operated by switch.

The bay is finished complete with a paper towel and soap dispenser, cable and phone outlets and black water flush.

Aqua Hot
While it is an expensive option an Aqua Hot system is the best heating and hot water system on the market. Eliminate hot and cold pockets typical with a propane furnace and provide more moist heat unlike a propane furnace that dries out the air.
