If you are in a very cold climate, condensation can occur behind the insulation if it's not well-sealed. This would be of lesser concern in a winter-rated RV or even a three-season RV.
In any case, using a good quality two-sided tape at the edges of all insulation panels/sheets is an effective means of preventing moisture-laden air from getting behind your insulation.
Maintaining lower humidity inside your RV during extremely cold conditions (typically below freezing) will further guard against condensation.
Here are some tips to reduce sources of humidity:
1. Pre-cook food before your trip so you can reduce evaporation from cooking.
2. Cover pots and use your exhaust fan if you have use of your shower, or if you need to use your cooktop. Boiling water in an open pot can be a disaster in deep-freeze weather!
3. Use a dehumidifier. If you are boondocking, there are low-wattage units which don't use an energy guzzling compressor.
4. It may sound counter-intuitive, but when it's extremely cold you might leave your closet doors open. Keeping the temperature up in the closets will keep you further from the condensation point. Also, try to not crowd your closets or pile items up against outside walls.
5. RV propane furnaces do not consume inside air for combustion, so without some mechanical exhaust - even if your rig is leaky, humidity can pile up quickly.
6. If you are shopping for an RV to use in extreme winter conditions, look for a rig with AZDEL exterior panels (I think Winnebago used to call it "Thermo-Panel.")
