    Anyone else have this problem? I am a brand new pop up owner...5th time out since we bought it (1999 Camplite by Damon) and of our trip we are on now...we had a lot of rain one night and since we have had moisture drops building up on the roofs of the bunk ends and then when we flip over or move in our bunks during the night it feels like it is raining on you - do we need to waterproof our canvas or something? Any help would be welcomed! Thanks!

    Do you have any openings for air circulation? Condensation inside is common in rainy or humid weather when there is not enough circulation. Bunk ends tend to be worse, since they are shorter ("floor" to "ceiling") and people are often in them breathing out humidified air, etc.

    Covering the bunk end canvas will really help, too. The pic below shows one of those plastic tarps over the bunk end and just the tarp by itself helps. But under this tarp is a layer of Reflectix insulation which helps enormously. Now you can buy an already made up cover called a "Gizzmo" which are easily installed. The outside cooler air temperature vs the inside warmer temperature, and depending on the amount of moisture in the air, will cause the condensation to form. Plus add some people breathing inside (generating some more warm moisture to the inside air), and you almost have a rain forest in the the bunk ends! Like already posted, the first order of business is to vent ... unzip some corners, open the roof vent a little (if it's not raining!) and there are the panels on the door that can be opened.

    This sounds like a classic case of condensation buildup due to improper ventilation of the p'up. Crack a couple of windows to get some ventilation and you should be all good.

    Yup. As the others said, open at least two windows a couple of inches, across from one another, for proper ventilation. Humans exhale huge amounts of water vapor over night. Also, getting Gizmos for the bunk end roofs ( to help keep cool/cold air out of contact with the canvas) is a great help. Gizmos help keep the PUP cooler when it's hot, too. And, they keep the canvas clean by preventing sap and bird dropping from getting on it.

    As others have mentioned, PUGs help a lot, by creating an air space above the bunk end roof. If you go in cold weather (<35-40*), the bunk end liners from PUGs help too, for warmth - when we did Grand Canyon in Nov. and the temps were in the teens to twenties at night, I found frost between the liner and tenting. However, I did not have a problem with condensation in the living or bunk areas, due to heater and air flow - in spite of hanging wet clothing inside (I walked for miles in the snow/fog).

    You may want to also turn a small fan on to keep the air moving in the PUP.

    I also learned (the hard way) not to touch the canvas from the inside if it's raining outside. It wicks.
