I love your window solution and will figure out a way to use one sooner or later. My point is you can't have it both ways. The example you posted is great from the outside. But you'd have to position your fridge so that it wouldn't open from the inside.I agree with being outside but there are fixes available for window access.
I wasn't knocking the pics posted above. Love them. Just saying from experience you're going to have to choose. Do you want an 80 you can live inside or an 80 you can hang around as a campsite?
