I am storing my camper outside year round and noticed it excess humidity levels forming inside in warmer months. It is being parked on asphalt driveway but surrounded by heavily wooded area.Running dehumidifier did not go to well because could not figure out how to run a discharge house to let condensate outside without cutting a hole in a camper lolAlso thinking of moving camper to a different area on my lot presently grassy area that willGet a couple of truckloads of crushed stone or pebbles over if. So the challenge is to protect the inside as well as the outside / underbody from excess humidity and elements.Any input is appreciated.

Put down a moisture barrier underneath the stone.

Concrete or asphalt would be the best to park it on as long as there is a "crown" or angle that allows water run off.Dirt/gravel is a poor choice, moisture comes right up through the ground and gravel.. Lots of vehicles rot from the underside very quickly when parked on dirt/gravel and don't get moved often..Your over thinking this, simply open a few windows slightly (even sliding windows can be opened slightly without fear of rain getting in) which allows the air inside the RV to be exchanged with the air outside the RV.. Inside of RV will not get any wetter or damper than the air outside..

I only close them in the spring when the pollen is ridiculous. Our old camper (bought used) initially had a mildewy smell when it sat in storage. After we started keeping the roof and window vented open, the smell went away and never came back.
