I am not familiar with your coach. However, FWIW, in our 2015 Baystar, the electric auxiliary heater unit, fan, air intake grill, and metal heat exhaust vent are all located together, at floor level, in the bedroom. These are housed in a space that is part of a group of wooden, pull-out, drawers. One, thick, black, water heater hose moves hot water from the engine to a small radiator in the heater. A small, electric fan blows air through the radiator, exhausting the heat, and the cool water is returned by another water heater hose back to the engine. The two water heater hoses, that form a big loop, are attached to the under side of the RV and are visible by looking up, under the coach. What I DON'T know, is if the auxiliary heater uses actual radiator water, or if it uses a separate pool of water, a "closed heat exchange unit". -That's all that I know. Have a good trip to Utah. That's a fantastic, scenic state.
