I think...just musing here...think if I lived up there again, and had some spare coin, I'd get a metal shipping container for a shed. This will be a shed/cobjob kiln. Have a vent or two high in the back, and low in the front by the door. I would pack it with fresh cut up to a few feet from the door. As soon as it is empty in the spring, it can be with wood cut in the fall or winter and left outside until it is empty. Then install a small smoke dragon just far enough inside to get the door shut, anything, one of those small cheap box stoves would be ok.. Cook it out for a few days with whatever dry junk wood you got. this should get it pretty darn dry already. Then do it again right before heating season, just because you can, and it would off any bugs that got in there and geet the last tiny bit of moisture out.. Let it sit and bake in the sun with the vents open in between those two cooking periods, like from spring until fall.
I think this would work better than a shed. I like the idea of all steel even over a wood framed steel building, nice tight closed container, closed except for the low cool air in, high, hot moist air out vents. proly wouldn't even need any fans, just heat from the cheap stove.
I know I have had to go out into road tractor trailers in the heat of summer, roll the doors up, zooba, it is rather *warm* in there. With just a couple of vents, you would get airflow to get the moisture out.
