Description

For sale is our exceptionally well-maintained 2006 Monaco Dynasty Diamond IV luxury diesel pusher with only 58,972 original miles.
If you're familiar with Monaco coaches, you know the Dynasty represented some of the finest construction and engineering available in a production motorhome. Built on Monaco's Roadmaster chassis and powered by the legendary Cummins ISL 400 HP diesel engine paired with an Allison automatic transmission, this coach delivers an outstanding ride, excellent drivability, and long-term reliability.
This coach has been carefully maintained and is ready to travel today.
Highlights
Only 58,972 original miles
Cummins ISL 400 diesel
Allison transmission
Aqua-Hot hydronic heating system (works perfectly)
1,449 generator hours
Four slide-outs
Tag axle
Desirable two-sofa floorplan
Tires replaced in 2023
House and chassis batteries replaced in 2023
Clean and well cared for
Interior
The Diamond IV floorplan offers a spacious and comfortable living area featuring opposing sofas, creating an open feel that is ideal for entertaining or extended travel. Solid hardwood cabinetry throughout reflects the quality Monaco was known for during its peak years.
The coach features:
Opposing sofas in the living area
Residential-style kitchen
Solid wood cabinetry
Spacious bathroom
Private bedroom suite
Excellent interior storage
Aqua-Hot heating and hot water system
Insta Hot for Kitchen Sink
Mechanical & Systems
Everything on the coach functions properly with one known exception:
Main patio awning motor currently does not operate and will need diagnosis/repair
Otherwise, the coach runs and drives beautifully and has been exceptionally reliable.
Exterior Condition
Exterior paint continues to show well. There is some clear coat peeling on the entry door and roof cap areas, which is common for coaches of this age. Outside of those areas, the coach remains very presentable and attractive.
Why This Coach Stands Out
Finding a Dynasty of this vintage with:
Under 60,000 miles
Working Aqua-Hot
Newer tires
Newer batteries
Low generator hours
Strong maintenance history
is becoming increasingly difficult.
These Monaco coaches are known throughout the RV community for their build quality, solid construction, excellent road manners, and luxury features. This coach offers the quality of a high-end diesel pusher without the cost of a much newer six-figure luxury coach.
Clean title in hand.
