"Moyafoto".....You didn't say if it's a short space with room for just an all-in-one unit or a tall space with room for a stackable unit. If it's the short space, make sure you get the VETED all-in-one as others mentioned. If it needs the vent hole drilled, Winnebago and see if they will provide you with a description as to where to make the hole, or find another coach with the option installed.
If a stackable or even the all-in-one, you need to see if they will come through the door or does the window/windshield need to be removed.
