ROADMASTER S-SERIES SEMI-MONOCOQUE CHASSIS 1 10,000 lb. hitch receiver offers powerful towing capacity with 7/4-way trailer plug. Pre-wired for supplemental braking system that works with your tow vehicle. 2 The three-point engine mounting system lowers the coach’s center of gravity and reduces the amount of vibration that reaches the coach. The mounting also makes the engine easier to service by allowing the engine to be easily lowered through the bottom of the coach. 3 Allison® 3000 MH 6-speed transmission for smooth shifting; our exclusive use of synthetic transmission fluid allows for up to three-year maintenance intervals. 4 Cushion Air Glide suspension system positions ten Bilstein® shocks and ten air bags, eight of which are outboard mounted with auto-leveling for greater stability, a smoother ride and the best handling in its class. Unique three-degree rear axle tilt perfectly aligns the engine, transmission and differential, minimizing stress on the drivetrain and reducing noise in the coach. Automatic Traction Control (ATC) eliminates wheel slippage in slick conditions and heightens control. Tag axle lifts for added maneuverability in tight spots. 5 Basement structure rust inhibitor. To prevent corrosion, the basement storage area is constructed with pre-primed steel with rust-inhibiting paint. 6 Full-length frame rails fabricated from 3” by 8” by 1/4” 60,000 PSI structural steel; rails are spaced 44” on center for a wider stance and unmatched strength. 7 The semi-monocoque design, with trussed superstructure, distributes stress evenly throughout the entire chassis and adds strength to sidewalls and bays. 8 Two-stage Jake brake system assures you of safely traveling steep grades while 6-wheel anti-lock brakes with disc brakes in front help you maintain control in severe road conditions. 9 P295/80R/22.5 Goodyear steel-belted all-season tires ensure a safe and quiet ride (G670 RV tire). a0 The TRW power steering box allows for a 50-degree front wheel turn angle in both directions for better maneuverability and returns the steering wheel to its center position to eliminate driver fatigue. aa All chassis are equipped with steel cage construction, steel firewall and steel stepwell for added safety. MAY WE BUILD YOU A CHASSIS? Did you know that every Roadmaster chassis is custom designed and built for the Monaco coach that will ride on it? It’s a novel idea, but our owners seem to like it. And it pays off — in better performance, safety and reliability. Owners also like the fact that Roadmaster, a division of Monaco Coach Corporation, only does one thing: They build chassis for motorhomes. Not trucks. Not buses. Just motorhomes. So naturally, they do it better. No wonder Roadmaster is the leading high-end diesel chassis manufacturer in America.
