You must have the hybrid with the 7,200 watt generator. The 2.0 and 2.4 won't run the AC. Well maybe if a soft start capacitor is added to the AC. I ran my TT with my 2021 F150 with the 2000 watt for a couple hours. I did not detect exhaust coming in. I topped off my batteries and fixed a little breakfast.
