How do you in the S/E handle high humidity inside your rig?

[D_E_Bishop]

Our nephew lives in Jacksonville on a side canal off the intercoastal waterway and he is having problems with mold and moisture damage in his small class A. It is so bad he is moving it to their second home in Colorado. He has been running the AC 24/7 in his rig.

Granular absorbent is usually the first thing I'd suggest along with adequate air flow but that hasn't seemed to work. What practices do you follow.

We live and often camp right on the intracoastal in NC. While it is incredibly humid in the summer, we don't have moisture issues in the FW. Not sure what the secret is but we don't do anything special. Our FW has real ducted AC, maybe that helps? Maybe better insulation? Maybe the more open floorplan helps?

First thing I would try is a dehumidifier, get the AC cleaned and make sure it's operating efficiently.

We had an entry level Class A once that held a lot of moisture. That thing was hardly insulated.

It's funny to see "Eagle Rock" and "Humidity" in the same topic. It's not something we have to think about much in CA.

We use a larger (22 pt., I think) compressor type dehumidifier in addition to the two 15K ACs. Some days the dehumidifier will pull 1-1/2 gallons of water out of the inside of the RV. That's a lotta watta! And it's not just in the southeast... we just had to use it in Iowa and Illinois with similar results.

Has he tried a dehumidifier, you have to provide a way to drain the water so maybe set it up next to a sink or in the shower with the door proped open. Need power 24X7. Our homebase is a few hours away but not on a canal, but 80+% humidity is high enough. No mold tho.

We don’t have too much issues. We run the roof ac with all windows and vents closed, making sure the dash ac had been set to recirc to make sure the damper is closed.

Get moisture down to under 50 percent and keep it there. Dehumidifier is the best way to do that.

Does he have power to it? In the rainy pacific northwest, when my RV is not in use I always run a dehumidifier in it. I set it on the counter near the sink and let it drain into the sink so I never need to empty it.
