The door swings out, so I don't see the space of the rack/tub a problem.

Our power rate is $0.037 per kWh...not overly concerned with running a fan.

I could see possibly removing the wood. We'll see. our RH here is typically 20-30%. We don't have mold issues like many places in the country. We don't have condensation happening like many areas, either. Not that we can't and won't have the problem, but we'll keep an eye on it and change if necessary. A roof this size won't be tough to re-do/re-figure.
