Humidity in a shelterlogic garage

[2StepsAhead]

I have a shelterlogic garage (read: tent lol), its 25x24 and sits on top of a concrete foundation...recently with a snow storm some snow blew in under the front door and it accumulated.

When I checked on the garage about two weeks after the snow I noticed my cars rotors had gotten rusty along with a bare motor I had on a stand. The snow melted and the floors dried but again the rotors seemed decently rusty after only about three weeks.

So my first question...is there really a cause for concern? I figure the rotors got rusty sitting outside in the rain before having a garage so is there much of a difference being indoors vs outdoors? Im not worried about the rotors per say, just assumed they wouldnt rust this quickly without water hitting them...I dont have a real garage to compare to.

If the answer to my first question is a yes, what can I do to help the situation? I have the two shelterlogic auto-opening vents installed...but the only open when they get to a higher temp. I was debating if I should force them open all year round.

Yes, unfortunately they are like green houses and the condensation can even rain down inside under the right conditions. I've had one for years and have learned it's more like a place to keep my junk pile out of eye sight than protect good things. The problem is with warm days and cool nights, the air inside is warm and humid and when the night comes, the cover cools off and the moisture condenses on the inside surface, even to point of dripping off the cover and metal frame. Not sure if there is anyway to improve it. To store a car you might even be better off leaving the north end completely open, it will protect it from the sun, but be ventilated enough that it won't build up moisture.
