on board environmental systems 8D

I have seen here many wonderful ideas for installing an (affordable window) A/C unit into a TD. I've seen them installed in the galley area, hanging out the side, even sitting on the tongue and remotely ducted into the Tear!
It seems like you would need either A/C or heater on a trip but not both (generally). So I was looking for a removable setup but have not seen a unit installed in a hatch or window in the front of the Tear (Ben Roy). When arriving at camp the window or hatch could be removed and the A/C unit installed quickly. Maybe supported by legs that can be unfolded to rest somewhere on the tongue. Would this eliminate the icing problem usually associated with the ducted systems?
Also, as far as heat goes, has anyone ever used one of these. http://www.coleman.com/coleman/colemanc ... oryid=3000
I have a friend who uses one tent camping. Thats what they are made for.
just thinking again,
