Condensation issues

Just FYI, I have owned two Entegra coaches (15 Anthem, 19 Cornerstone) and live in and travel in Louisiana and I have never had a condensation problem like yours. That could be because we live differently, or different conditions, or maybe build of the coach. I am just guessing but wonder if you do still have a leak and you just have not found it, or maybe insulation was left out of that area that should be there.

And a minor note, but the places that look for leaks professionally (as a business) often use the opposite process.... they try to increase the air pressure inside the coach while spraying a thin coat of soapy water on the area in question outside and see if they see bubbles forming where there is the passage of the air.

And you know, my, and probably your, primary concern is the build-up of mold and mildew in your coach between the walls. This is the sort of problem that a good dealer or Middlebury will tackle under warranty. If you are still under warranty, I'd be documenting the problem with Entegra CS soon.

As was anticipated and typical, Entegra immediately stepped up and offered remedy to our condensation issue. They also do not have a problem with me taking steps to correct it myself as our service appointment is not until May. They indicated although there have not been any additional complaints regarding condensation in the area above the door, they have had numerous leaks develop in that area and want to be sure this is not the case for us.

Once again, this was exactly the response I expected based upon our almost 5 year history with the company. We have owned both a pre and post Thor coach and our concerns have been handled with the same great customer service in both instances.

We had this same issue on our '17 Aspire, however it was the front inside of the cap and the water dripped onto the dash from the overhead liner. I think the factory has since taken steps to eliminate condensation from occurring in this area. It woud appear they need to extend these efforts to at least the door side of the cap and I suspect, most likely, both sides. Admitedly we have just experienced a worst case scenerio for condensation. Rain, meaning high humidity, and extremely large and rapid temperature drops. So much so the inside of the windshield was condensing copious amounts of water. Anyone else having, or had, this problem? What remedy did you employ? I'm considering some spray foam as simply batt insulating the area without a vapor barrier won't accomplish a fix.

Oh Yes... The condensation issue arises again in the winter months.
Do you keep your ceiling vent cracked open a bit? This helps to dispel some of the humidity. Next, use a small dehumidifier. (https://smile.amazon.com/s?k=small+d...ss_ts-a-p_1_11)
Check your cabinets. We have condensation along the top edges where the aluminum frame is covered by the wall board. I have put 1" x 1/8" foam insulating tape over these areas. This helps greatly.
I hope you can resolve your problem soon. Mold will start to grow if this is not addressed aggressively.
Happy trails.

Lower the humidity during winter months. Cheap & easy way is to get DampRid or similar product. They really do work well (usually collects water you dump out). Some are disposable, some refillable. Many (of course) r available on Amazon and may be in local hardware stores.

I know exactly the conditions you describe that lead to this problem. We have similar issues with the windshield and driver windows and sometimes other windows condensing copious amounts of water after a weather change. We don't have the water dripping problems though.

Warm, humid (maybe even need air conditioning) weather followed by a cold front. We just had a similar event.

It is a good idea to get an indoor humidity monitor so you can keep track of what's going on.

Our indoor RH was about 50% during the warm weather. When the temperature started falling outside the humidity went up to as much as 66% for a few hours. That's when the condensation happens. The cooler air inside can't hold as much moisture. Windows and un-insulated places are below the indoor dew point. Starting the heat pumps aggravates the problem on the first run because the evaporators (now condensers) are soaking wet from previous air conditioning duty. Now they are heating and all this moisture is evaporated and added to the coach humidity.

As others have pointed out, opening a vent or window during this transition period helps. Even cold humid air will be drier as it is warmed up inside the coach. In a really big temperature swing, I open cabinet doors and check for condensation in cool places until things have had time to settle down.

Our humidity has fallen from the mentioned high of 66% to a more normal 48% now. During most of that drop it was raining out with near 100% humidity and near 40 degrees. I expect it to drop more to less than 40% since the rain has stopped. We were cooking and stuff inside too. We always vent the shower humidity in cold weather too.

It takes a day or two to readjust to the new conditions, then everything is good again. Maybe they can install some insulation and vapor barriers to stop the condensation in your cap area.
