As part of the preparation to store the camper over summer I'm installing covers over the roof vents so that they can be left open. Our greatest worry about leaving the camper for unattended for 2 months is mold. If it molds it could be really bad and even unlivable because my wife is very sensitive to mold. Our hope is that leaving the vents open will help the air circulation and lower the risk of mold.
If we could I'd love keep to leave a dehumidifier running but we can't have power and running it off solar is not feasible. A thurrow cleaning, inside and out, plus as good ventilation as possible have to be enough.
