I often get asked why we chose an 18-year-old motorhome, and my answer is simple: because they don't make them like this anymore. Our 2006 Monaco Diplomat 38PST isn't just an RV; it's a testament to quality construction, incredible engineering, and the freedom of the open road—without the hassles of modern emission systems.
When we purchased this coach in 2023, the odometer read an unbelievable 6,000 miles. Some called us crazy for buying a "vintage" diesel with such low miles, but we took the plunge. After a meticulous tune-up and installing Brand New Hercules Strong Guard HTL Tires, this Monaco has been absolutely flawless. We've put 7,000 miles on it in two years—from the plains of South Dakota to the peaks of Banff—and have experienced ZERO mechanical issues. That proven reliability is why I love it.
The Sweet Spot: Size, Power, and Comfort
The 38-foot length is pure genius. With the three slide-outs open, we have all the residential space a couple could ever need, yet it still fits comfortably into almost all State and National Park campgrounds. This gives us access to places bigger coaches can't reach.
Underneath the beautiful full-body paint is the legendary power train:
Pre-DEF Cummins ISL 400 HP: Power without the Diesel Exhaust Fluid hassle. This engine is a proven workhorse that laughs at mountain passes.
Roadmaster Chassis & Allison 3000 MH Transmission: This is the gold standard. The Roadmaster chassis provides a smooth, stable, car-like ride, and the Allison transmission shifts effortlessly. It's a true driver's coach.
Interior Upgrades that Make it Home
Monaco's construction is known for its quality wood cabinetry and solid surfaces, but we customized the living space to make it perfect for us. Swapping the factory sofa for a cozy recliner loveseat turned the living area into the ultimate relaxation spot. Add in the new Queen Mattress and porcelain toilet, and you realize every essential comfort has been addressed.
This motorhome has taken us on the trips of a lifetime, including a recent 3,000-mile journey through the Tetons and Yellowstone. It handled every road and elevation change with grace, keeping us comfortable the entire way.
If you are looking for a reliable, turn-key, low-mileage coach from the best era of diesel pushers, our Diplomat is truly exceptional. We are sad to see it go, but excited for the next owner to create their own incredible adventures in this meticulously kept machine.

This coach is in great condition and has been well maintained and cared for. Professionally remodeled this year, upgrades include new flooring/carpet and new XL residential shown.
All the service records are available upon request.
The Cummins ISC 8.3L 350hp engine and Allison MH3000 6 speed automatic transmission are the heart and soul of this coach. Designed to run 1,000,000 miles without major service, you’ll have confidence pulling mountain grades with your tow vehicle.
Amenities are too many to list. For in depth amenity list please go to Monaco website https://www.monacocoach.com/library/2002/2002_Windsor.pdf

Great Coach, dives/handles like a dream, don't even know you're towing while cruising down the Interstate.
Solid construction throughout, the interior is exceptional in comfort and design, affording complete livability whether for a vacation or full time living.
Good visibility, excellent since there is no center bar in the middle of the windshield only a clear unobstructed view, both while driving and set up.
So much storage space, for full timers, you can bring all your gear with you and the kitchen is great for the Chef, ample cupboard and counter space to prepare the best of feasts
HVAC, generator, all components are quality and importantly, quiet while using them, only a whisper to hear while inside the home.
