condensation inside
We have a 2015 24fbs TT with the thermal package. This last trip we noticed heavy condensation on the inside walls and windows. Has anyone else had this problem?

Anytime we notice condensation, we crack a window and a roof vent for circulation.

If all the windows and vents are closed tight, you'd likely experience some condensation - worst as the number of belly bottons in the trailer increase and the inside to outside temperature difference increases.

My roof vents are always open a little while the RV is occupied, and usually a window in the bedroom while we're sleeping.

We crack a window, near each sleeping area. It does not need to be much. We also crack open the roof vent in the bathroom about a 1/2". Works great!

Also see what you can do to reduce the creation of moisture, for example: make sure bathroom fan is on when showering, consider how much steam is being generated on the cooktop (e.g., coffee, boiling pots), and do like many of us do - have dehumidifiers.

We always leave our vent cracked, rarely a window as well. I don't worry too much about it on the windows (there are weep holes for that), but when it gets on the walls, I'll crack a window or two in addition to the roof vent over the bathroom. That's pretty rare though.

Yes, we have same model and noticed for the first time a couple of weeks ago when we were out and had warm days and cold nights. Sounds like a lot of good tips to try, and it will be soon as were taking it out for New Years weekend. I'll let you know.

This guy says that propane heat produces water. If true, I just learned something about condensation in RVs.

Yes, it's true that one of the byproducts of propane is water, but none of it from the furnace or water heater can reach the inside of a trailer since the exhaust is all vented outdoors. But using the range top and oven will cause the humidity to rise inside an RV.

All that is true, but the heater in a RV draws its combustion air from outside and the exhaust routes all if not most of the humid air as a result of combustion outside. The warm air that is used to warm us inside comes from a heat exchanger.
I think the majority of condensation in our rv's is from the difference in outside vs inside temperature. The moisture from combustion is negligible using the type heater in modern rv's.
Moisture can however be a problem especially if the unit is closed up.

We started running a dehumidifier when we full timed, and it just carried over to the present rig. It works, probably better than any other method. Yes, we run the fan in the bath when showering, but I don't like leaving windows and vents open, so when it's time to shut down for the evening, the dehumidifier takes over. And let me tell you, towels are dry in the morning, my sinuses are dry, and the camper feels very dry. The dehumidifier just works. No sweating windows, no muggy feel etc etc.

True. Propane is clean burning, but produces residual water that must be disposed of, usually through a vent pipe. It took a half a century, but that C in college chem finally paid off!

Yes with ventless propane but not with RV furnaces that are vented to the outside.
