2006 Monaco Signature Low Mileage, Owner-Maintained, Indoor Stored

This 2006 Monaco Signature diesel pusher is a rare, well-preserved example with just 31,000 miles. The coach has enjoyed dry climate indoor storage and is meticulously maintained by the owner, a commercial pilot and former CEO who has personally overseen all service and maintenance. This coach has never required cosmetic restoration, rehab, or paint work to present exceptionally well. The coach has been maintained with the same discipline and attention to detail the owner applied to his company and his ownership of numerous high performance aircraft.

Upgrades & Enhancements

Air-brake hoses replaced with top-of-the-line Parker steel-braided hoses and fittings for maximum safety and longevity

Upgraded Victron inverter (lithium battery ready)

4K Sony television and color display Wi-Fi-enabled thermostats.

Engine & Mechanical Condition

600 HP Cummins ISX CM engine

Recently serviced and inspected at an authorized Cummins factory facility

Completed a comprehensive 30-point inspection

No recommended repairs or deferred maintenance noted

Full transmission service including filter and fluid exchange

Recent roof periodic re-seal completed Fall 2025. Generator maintenance & service done.

This coach is equipped with the highly desirable 600 HP ISX engine-- not the later ISX 650HP calibrations introduced two years later in 2008. Those engines had a history of valve-train and EGR-related wear concerns. Those later, higher-output calibrations which caused service issues are not the 600 HP configuration in this coach. This distinction is supported by Cummins service data, engine data plate, year model, and recently confirmed by recent factory inspection.

Paint, Body & Storage

Dry climate indoor storage

Near showroom-quality interior and exterior, achieved without repainting, cosmetic manipulation, or cover-ups.

Interior and exterior condition is rated as near new and excellent. No observed paint checking, sun fade, or environmental degradation typical of outdoor-stored or neglected coaches.

A Note on Rehabbed Coaches- And Why This Monaco Signature is Superior

Some older high-end coaches have undergone rehabilitation after they first experienced significant wear, prolonged outdoor exposure, excessive humidity, deferred maintenance, or cosmetic decline. While a rehabbed coach may look impressive in photos, underlying or hidden issues may exist from its past history of outdoor exposure or neglect. Such as hidden corrosion, frame or suspension problems, moisture intrusion, rodent damage, dried out bushings, etc. Hidden problems may be lurking below newly painted or buffed out finishes. These problems may be hidden even from the rehab middleman. Finally, the need to turn a profit on rehab coaches acts as a governor on what gets addressed-- and what does not.

This Monaco Signature has never required rehab because it was properly cared for from the start. It is a better route to preserve the integrity of the entire coach compared to choosing deteriorated coaches then rebuilding selected portions or systems. With this coach, you can discuss its history directly with the owner. Rehab/flippers may not even know where the coach came from, what its history of decline was, or how many owners it passed through.

Why This Coach Stands Out

This is not a broker-flipped or cosmetically refreshed unit. You are working directly with the owner, who can provide full transparency on service history, upgrades, and inspection results. Maintenance has been proactive and preventative, not reactive.

This 2006 Monaco Signature represents a rare combination of:

Low mileage

Indoor storage from new

Verified Cummins factory inspection

Proven engine configuration

Long-term, knowledgeable ownership

It looks, drives, and presents better than many significantly newer coaches, offering confidence, performance, and longevity without the uncertainty and risks that often accompanies restored or rehabbed units.

Premium Features:

1. Low mileage, well maintained, stored indoors.

2. Interior & exterior condition reflect its history of care and indoor storage.

3. Cummins ISX 600HP Diesel Engine w/Allison transmission.*

4. Luxury throughout, top-of-the-line, "Signature class" vehicle.

5. 12,500 Cummins diesel generator.

IMPORTANT NOTE: This coach is equipped with the 600 HP Cummins ISX, the version that predates the 650 HP variant introduced in 2008. The later engines included engineering changes and higher output, which contributed to some reliability issues.

Please be aware of inaccurate claims that conflate this proven, reliable 600 HP engine with later variants that experienced problems due to engineering changes and horsepower increase. This distinction is important for buyers to separate rumors from facts.

Hydronic (Aqua-Hot) Heating

Some of the rehab coaches advertise heated floors, possibly to overcome a deficient coach heater to begin with. This coach goes further with full hydronic heating via Aqua-Hot. This system circulates heated fluid throughout the coach for even warmth, quiet operation, basement protection, and unlimited hot water benefits that floor-only systems cannot provide. With hydronic heating, there is quiet and luxurious heat in any climate.

Need to do a cold morning engine start? Flip a switch at the driver cockpit and the Aqua-Hot also circulates its hot water through the engine to pre-warm it before starting. Aqua-Hot systems are the "gold standard" in RV heating technology.
