I am in a 2026 Freightliner with an APU and a thermo king thermostat. The only sleeper ac/heat vents this truck has are 2 right above the thermostat. Therefore the air was blowing directly into my face as I slept last night. I woke up with a big drop of blood on pillow, most likely came from my nose bleeding from dry air. Should I sleep with my head the other way? Also, I need help understanding what tempature to set it on. I turned it on heat 70 degrees last night and it was just blowing…
