They blow in, when you say mount inside do you mean inside the compartment or inside the camper? There is little or no room inside the compartment for any type of fan. I don't know if the panel on top of the refrig. is just a blank that I could cut into or not. My best reason was it's not permanent, I can just put on the other panel and the unit is back to stock.
No, I will take a picture tomorrow. I may have had room for one fan but would have had to wedge it between the coils. I didn't want to do that with the heat they gererate.
