Where I live, the humidity rarely drops below 54% and can be as high as 98%. 2/3rds of the year has measurable precipitation and that does not count the days of drizzle that don't move the rain gauge.
Rot, mold and moss is a major issue with RV's in this area so location does play a big part in what type of problems we have to address. We really don't get paint fade or rubber deterioration here like in some states. You can find cars with original paint and interior here that are 50 years old and lived outside their entire lives.
In the same area as Bedlam and we are running a 115V dehumidifier in our camper while it is under construction. Before the dehumidifier I measured the RH and got readings of 85 to 95%! and the camper is in a dry garage. Now it is constant 35% but I have to empty a quart of water once a week if we open the temporary door a lot.
