We have been having trouble with condensation. We sent pictures to our 5th Wheel manufacturer and the replied as shown below. I guess my question is, how close does the inside temperature have to be to the outside so condensation doesn't form. We have purchased a dehumidifier, but the temperatures have been in the 60's the last few days. Any thoughts? The reply is below: I got both of your pictures and reviewed them. Your camper has aluminum framing. Where the condensation is occurring is where the frame is. What is happening that aluminum is much colder than the inside of your camper. You need to open your roof vents, reduce your heat and get a dehumidifier. Unfortunately, like I had stated before the warranty does not cover condensation. If there is anything else that I can help you with please let me know.
