Lee's advice rings true and is similar to much input I have recieved about referigeration.
I especially want to comment on the line "Try to route the output air somewhere that you want dried out." This works like a charm. I did that with all the plywood involved in a closet, a settee, a berth, the head and the shower in my aft living quarters. When the AC is on much of the return air is drawn through all these dead spaces (actually in-use lockers, much bedding, winter clothes, seldom used galley gear). I have absoutely no mildew problems. Of course, the hull has foam unsulation over every square mm so there is no condensation at all. I should put a voltage sensitive computer fan somewhere on a voltage sensitive switch so it would come on when the battery voltage is high (charging).
