Travel trailer

[NancyLepri]

I hsve a friend who owns a travel trailer. They took it camping when it was pretty cold in Michigan. Turned on the heat at night and the windows got condensation and dripped water down the walls. Is that normal?

crackin the windows and vent doesn't work for me, I guess I sweat too much, and my 150# dog is constantly panting too, so that's a lot of moisture in a 20ft trailer. A nice and quiet Frigidaire 90 pint dehumidifier keeps my cabin comfortably dry, and it gives off a nice amount of heat too, so the furnace runs less.

It takes a fair amount of power (about 800 watts), I can only run intermittently while on inverter, but on generator or shore power, it's on all the time.

Could run a small dehumidifier but opening a window or running the bath fan works

Use an extra blanket and turn the furnace off at night; this has worked for us
in the past when camping in 20-30 deg F weather.

Completely normal but not good

Thanks for the info. I am going to have her get on this website. Love Rv.net!!

Normal if they are breathing, washing, or doing other things that put moisture in the air.

Condensation works in this case just like the drops running down the side of a cool drink on a hot day. The moisture in the air condenses on the colder surface.

Is it just the windows or do the walls "sweat" also?

Could the windows be infilled with foam insulation panels to stop this?

But not normal or good for TT to drip down the walls!

Yes.. That is a chronic problem in a TT if you don't have air flow.. Was their heat forced air? That will help. If just static electric heaters, the moisture from a lot of people's breath, showers,and cooking will cause condensation and water on walls which can over time destroy the TT due to delamination inside the walls.. You always need to vent even when cold out by opening one or more roof vents to allow moisture to escape.
