I agree with Timothy. After a career in oceanography and 20+ years of sailing, I've concluded there is no such thing as waterproof. Just varying degrees of water resistance.
Condensation happens when warm, moist air meets a colder surface and gets chilled to the dewpoint. Ventilation ensures that everything is at the same temperature. I don't know how much heat the M4 puts out, but it's probably enough to keep the surfaces warm relative to the incoming air.
