In the old days the brochure said this: »The floor is insulated with a layer of heat refective astro-Foil plus a layer of fiberglass insulation equaling an r-21 value. Most importantly, the water lines are installed between the floor joists, near the heat duct and above all of the insulation and the heated underbelly.
»The holding tanks and dump valves are completely enclosed, insulated and heated.
By that they meant that the tanks were heated by residual heat from the ductwork. Some of the owners of the newer rigs seem to feel they have actual tank heaters, but I've never heard Keystone say that.
