This is a very common situation in humid climates... and even worse when it is raining and cool.
Other posts have the diagnosis. Interior humidity and outside cool creates condensation within the interior.
Cooking on the propane stove creates heat and in the process water vapor as a byproduct. Your cooking heats the water, it becomes additional vapor and condenses on the aluminum ribs that are riveted. The burning of propane creates energy, CO2 and water vapor...
Sometimes, you just have to run both ceiling vent fans, crack some windows open and run the furnace, temporarily. Otherwise your bedding will be damp, the pillow is damp, your clothes are damp.... and you become miserable.
We keep a "interior and exterior" weather station purchased at Costco. We know the exterior temperature and humidity, as well as the interior's temperature and humidity. When the humidity begins to climb... you need to run the vents and get fresh air heated, which lowers the interior humidity.
When raining... you have the worse of both options.
You would be envious camped in the Western USA when it rains the interior humidity is much lower than the humid Midwest. During nice weather the exterior humidity may be 18% and the interior... 3%. This is a real plus if you are camping in your trailer and above 3,000 feet elevation where the humidity and air begin to improve your comfort level.
Although at 8,000 feet you will find condensation on the exterior of the trailer until the sun warms the air and it quickly is gone. Go in DRY, and leave WET for the real high country. Thin air does not hold the water vapor as well.
Living at 6,000 to 7,000 feet elevation... you may not even sweat while working hard and not drink water. Later to find leg cramps and lack of water fatigue. I drink 48 to 60 ounces of water a day... just to keep hydrated. Now you understand why camping at elevation is something to experience.
When raining... open vents, crack open windows and run the fans. Otherwise... see you in the Rockies this Summer. It will be absolutely beautiful and the humidity is something you will notice immediately.
