Our 2022 Mallard M335 is supposedly pre-wired for a second air conditioner (in the bedroom). I am assuming it would be placed in the bedroom ceiling air vent location. We would have had it installed when we bought it but Camping World did not even have one at the time. Is there a second thermostat somewhere or does it use the one in the living area? I am pretty worn out with trying to get info about anything from Heartland. We could get no information on whether there was enough reinforcement (there IS NOT) for installing a tv in the designated lift up area so we went 4 months with a tv on a stand and no storage access. I would also appreciate any suggestions on the brand/type of air conditioner anyone would recommend. We are living in our unit until our house is built so AC is a necessity. Thanks so much!
