Hi I am new to the heartland forums , Im trying to figure out if its possible to heat only the bedroom portion of the 5th wheel trailer while staying at un electrified campsites or Walmarts while on my way down south. Im interested in having the furnace come on less to preserve the battery life. will be staying at a 55+ RV site once we get there so not a problem then. Heading south soon from Saskatchewan to Apache Junction AZ. Will likely spend a couple cool nights in a parking lot in a few places. I should also mention the thermostats are both in the hallway of our camper near the bedroom and would be behind a closed door that we can seperate us from the living room and kitchen area. Has 2 thermostats cuz it has 2 air conditioners I guess. One doesn't seem to run the furnace only the one closest to the living area. there's also a fresh air duct outside the bedroom bathroom area we would be heating. Im also guessing the thermostat controller has a built in sensor that senses the temperature as I don't see where else it would sense temperature from? Any information is much appreciated.
