Two things. One is your camper is 110v. So depending on whether you're plugged into a 15a, 20a, or 30a 110v outlet, you could potentially run the AC.
If your stat is like my dometic digital, switch to fan, then press the + or - Buttons until it says auto. then switch back to heat and set your temp. If the fan is set to low or high, the AC fan will run at the same time as the furnace.
