For superior front-to-rear balance and overall performance, you can’t beat the Roadmaster RR4S. Roadmaster chassis are customized to the exact specifications of each Safari coach model and include many distinguishing features that make them the right chassis for your luxury motorhome.

• Cushion Air Glide suspension provides a smoother ride with excellent handling
  and cornering.
• The Zanzibar’s side-mounted radiator increases cooling capacity and allows for easier
  engine access.
• The SmartStructure® basement truss system, combined with the raised rail chassis, provides greater strength and structural integrity while reducing weight and increasing storage capacity.
• A wider, 34½ spacing between the frame rails offers greater side-to-side stability. The rails also widen in the rear of the coach to accommodate engine access.
• The full air brakes with Automatic Traction Control (ATC) and anti-lock braking system (ABS) offer superior control. The ABS system maintains traction and steering when braking on slick surfaces, while the ATC system eliminates wheel spin during acceleration.
• Adjustable brake and accelerator pedals let each driver adjust to the perfect position in seconds, at the flip of a switch. Together with the tilt-telescoping steering column, this system greatly reduces driver fatigue.
• A PAC™ exhaust brake system allows the driver to
  use engine exhaust braking on long downhills, saving brake wear and enhancing safety.
• Dual fuel fills provide the convenience of filling the fuel tank from either side of the coach.
• A 10,000-lb. hitch receiver gives the coach powerful towing capacity.
