6-LAYER FLOOR

Your fifth wheel features a six-layer floor and a fully enclosed, heated and insulated underbelly. The smooth underbelly contains freshwater and wastewater tanks, dump valves, wiring harness and heating ducts, which help keep the fluid tanks from freezing and improve the overall insulation factor of your Dune Chaser. The smoothness of the underbelly provides unrestricted air flow that results in easier towing and improved gas mileage. And the outer shell of the undercarriage is made of rugged composite material that withstands damage from road debris. In addition, the frame is coated with a rust-inhibiting paint.
