The 2007 Monaco Signature is a premium Class A diesel motorhome by Monaco Coach Corporation, part of their Signature Series line. It’s designed for luxury touring, long distance comfort, and includes high‑end amenities, multiple slide‑outs, strong engines, and upscale finishes.
The Signature series from Monaco is among their top‑tier, luxury coaches introduced in the early 2000s to compete with other high end motorhomes (Prevost, Newell, etc.).
The 2007 model year represents a period where emissions regulations were tightening, so many of the Signature MHs of that year have updated diesel engines (Cummins ISX, etc.) and associated emissions controls.
Monaco built these on heavy duty Roadmaster S‑series (or S‑10 / Roadmaster raised‑rail) chassis and with multiple configuration options (number of slide‑outs, trim packages).
Here are the engine / drivetrain options and performance aspects for 2007 Monaco Signature:
| Engine Option | Horsepower | Torque | Transmission | Chassis / Drivetrain Notes |
|---|---|---|---|---|
| Cummins ISX 525 hp | ~525 hp | ~1,650 lb‑ft torque | Allison MH‑4000 6‑speed | Used in models like the 40′ Platinum IV Signature. |
| Cummins ISX 600 hp | ~600 hp | ~1,850 lb‑ft torque | Allison MH‑4000 6‑speed | Found in larger/fancier variants like 45′ Noble III, Commander IV etc. |
| Cummins ISM (~500‑hp) | ~500 hp | ~1,550 lb‑ft torque | Allison MH‑4000 / similar | Some lower‑powered/earlier configurations had this engine. |
Other performance features:
Jacobs 2‑stage engine brake in many configurations.
Air ride or air suspension system with multiple airbags and shock absorbers (Bilstein etc.) for smoother ride.
Automatic traction control.
Exterior & structural features:
Heavy‑duty steel superstructure, with steel cage cockpit construction.
Laminated gel‑coat fiberglass sidewalls.
Seamless one‑piece molded crowned fiberglass roof.
Dual side (and triple head) power‑controlled heated chrome exterior mirrors; some with cameras. Full‑body deluxe paint finishes, optional fade graphics.
Interior and livability:
Multiple slide‑outs (2‑4 depending on layout), including full wall slide outs.
Luxury cabinetry (cherry or spiced maple), Corian countertops, tile or premium flooring in main areas; carpeting in bedroom in many trims.
High end kitchen appliances: residential‑style refrigerator, convection microwave, multiple burner cooktop, double sinks.
Luxurious seating in driver & co‑pilot: heated, power adjustments, sometimes with memory, power footrests.
Entertainment features: multiple TVs (living room, bedroom, sometimes external), satellite systems, integrated video coach systems (such as Aladdin), premium audio.
Other convenience features:
Automatic slide toppers / awnings (Girard, etc.), power door awnings, powered double entry steps.
Large holding tanks (fresh, grey, black), external service centers, outdoor electrical and water hookups, etc.
Some of the trim / variant names used for 2007 Monaco Signature include:
Noble III (e.g. 45′ models, higher power 600 hp engines)
Platinum IV (e.g. 40′ Platinum IV)
Commander IV (45’ Commander IV)
Fortress IV (45’ Fortress IV)
Series names like Series Castle, Fortress, etc., exist mostly to denote different arrangement of amenities & styling.
Trim / variant differences include number of slide‑outs (from 2 to 4), level of finish (cabinetry, flooring material, décor), optional packages (e.g. solar panels, external TVs, upgraded audio, collision avoidance systems), etc. bus-stuff.com+1
Safety features & tech included / recalled:
Standard safety features: integrated pilot & co‑pilot three‑point seatbelts. Smoke, LP gas, and carbon monoxide detectors. Fire extinguisher.
Dual‑pane safety‑glass windows, tinted. Egress windows. Deadbolt locks, safety grab handles, etc.
Back‑up alarm, rear vision cameras, color rear vision systems in many units.
Recall issues:
There was a safety recall (07V481000) related to driver seats built by Villa International: certain 2006‑2008 Signature models had seat lower slide rails of the air suspension that could fail, leading to potential separation of the seat from its pedestal in a crash. Monaco installed reinforcement tethers free of charge.
Also a recall for windshield wiper motors being under‑fused: the fuse might fail, affecting visibility.
Additional tech features:
Collision avoidance systems (Vorad) in some high‑end versions. Automatic leveling systems.
Engine braking (Jacobs) to help descend grades.
As is usual for large diesel‑Class A coaches, fuel economy is modest. Official mpg figures are not widely published, but typical diesel Class A motorhomes in this weight class (gross vehicle weight ~50,000 lbs) with 500‑600 hp will often see around 6‑8 mpg highway under good conditions; lower in mixed or city driving.
Efficiency depends heavily on configuration (engine, aerodynamics, drag from slide‑outs, weight, load, driving speed).
Some owners report issues from emissions‑related components (EGR etc) especially on 600 hp ISX variants; these can affect fuel efficiency and maintenance.
Compared to similar luxury Class A diesel motorhomes in 2007, such as:
| Competitor Model | Engine / HP Comparison | Amenities / Size | Relative Strengths / Weaknesses |
|---|---|---|---|
| Newell, Prevost, Beaver, Foretravel | Many offered comparable or higher craftsmanship, sometimes better build quality, but often more expensive | Possibly more custom options; Monaco pushes a lot of features as standard or optional | Monaco Signature has strong feature‑to‑price ratio; some competitors may hold value better, or have fewer mechanical/emissions issues over time |
| Other Monaco Lines (Dynasty, Executive) | Similar engines but differing on finishes, layouts | Signature tends to be more luxury‑oriented and full‑featured | For buyers wanting maximum amenities, Signature is top within Monaco; for simpler needs, other lines may be more economical |
When new, the 2007 Monaco Signature models with high‑end trims (600 hp, multiple slide‑outs, full luxury appliance and décor packages) were among the more expensive in the RV market.
Used value (as of recent years) depends heavily on miles, condition, maintenance, and which engine/trim: units in good condition with 600 hp ISX engines and lots of features often trade for $200,000‑$300,000+, depending on mileage and condition.
More modest trims (525 hp, fewer options, less slide‑outs) tend to come in lower used‑price ranges.
Specific awards for the 2007 Signature series are not well‑documented in the sources I accessed.
It is regarded in RV forums and among owners as a high luxury standard for its time, especially for its ride comfort (air suspension, high torque engines), build quality (fiberglass roof, full‑body paint, etc.), and amenity level.
The Monaco Signature line generally gets praise in “best luxury diesel motorhome” comparisons in period reviews.
