hqve been living in camper in MN since Christmas. Notice water dripping from ac vent. Opened it up and notice the roof was damp the insulation is damp on top but not all the way through. Some spots have ice. others are dry where there is more space between the insulation and roof. Is it a concern or no. A lot of people live in campers I have seen around here. So can't be the only one that has moisture. .

Any leak is bad and will rotten your wood. May need to replace your seal around AC.

The roof is wet all over. Front, back, middle. It's anywhere there is not a good amount of space between roof and ceiling. The camper is brand new I checked all the seals before this winter and everything looked good.

Also the temps here are around -10. The walls on the slide have frost forming. So I'm guessing it is a condensation from the roof mixing with the heat from inside. Not even area to make a good neutral area like in a house attic.

Mitch... you are correct about the condensation......just not enough air space.......warm inside air condensing on outside skin. You will notice rvs do not have a vapor barrier on warm side like houses. Its bad where you are but we even get it in humid but warmer areas. Not much you can do except try cracking a vent or window to make the inside air drier.

We are at 30% humidity inside. Temp with 3 heaters is 75 ish. During the day now that the outside temp is 30 ish. Should hopefully dry that roof. But long term shouldn't root the roof, Should it?

I'm not that familiar with the winter freezing moisture, but would a dehumidifier help? I'm wintering in AZ and just crack the windows when they start steaming up, but I don't run the heater at night and I'm only dealing with night temps in the mid forties most of the time.

There is a reason that people generally don't full time in RVs in harsh winter conditions. The Rigs were never designed for it. I would worry a great deal about roof rotting.

I wrote several posts on this subject, starting back in November, 2014 on exploRVistas.com. We spent that winter in Michigan taking care of my wife's mom. A dehumidifier is a must, along with running an exhaust fan when cooking and showering. Humidity is your worst enemy. We have MaxxAir vent covers and we found that leaving the bath vent open actually helped cut down the humidity. We also skirted the rig with 3/4" foam board. Also, electric heaters don't generate humidity like propane does.
Good luck!

Hi, Diana and Jim, and thanks for the link! As we're going to spend our first winter in humid area, so we were looking for some tips. The trickiest part for me is a proper air conditioning and dealing with excess humidity, so we have already traded our big propane heater for an electric one. Though, I must ask - you have mentioned that you have EvaDry, but as I checked it's pretty small. We were thinking about getting a bigger dehumidifier, but now I'm confused - would it be an overkill for our RV? Which humidity level did you keep through the winter? Thanks in advance!
