I and several other people here use a stand alone roll around 12,000 btu ac unit that vents thru the side wall and runs off a generator...now I will be changing to a 8000-10,000 btu WINDOW ac unit that i will mount in the pass door side window on a mount like those old food window trays that we use to get at the "drive in" . They are in the 16 in high 19 in wide area and will fit in the window and allow the window to roll up enough to keep it in place and fit a "filler" in the area to the front towards the door frame....OVM does this now...I would never put a roof top unit on...for the reasons you stated. The window unit is small enough it won't be an issue when in the back and not in use or in the way for freight.
