I have a Swift camper model and while the fantastic fan is nice there were some midsummer days I chose not to camp here in the deep South. Our missions are never more than 2 nights and a cooler sitting outside is always enough for our purposes. Is it possible to remove the fridge and put an AC in its place? The Honda 2000 is no problem to bring along. Do the window units actually have to be hanging out like an an apartment or can they be contained? Some of the small travel trailers have a window AC with the back end flush with the exterior.The face of the AC would sit flush with the cabinet and would make a drip tray of some sort under it that drains down. Would obviously run the fridge circulation fan and make a cabinet above the AC to fill the extra space. Would this work?
