Tarptents

You can minimize condensation by selecting slightly higher ground, camp away from water/lakes, and pitch the shelter as high and open as possible. You will experience condensation with TarpTents, on some occasions, possibly many in your location of usage.

Also consider a tarp and bug bivy, Mountain Laurel Designs for one, makes excellent tarps and bug bivy's

Dan I live in South Carolina, so I know exactly what you are talking about. I have a double rainbow, and so far I haven’t had any problems. The times I have used it I have rolled up both doors on both sides. Henry makes a 4oz liner to help with the issue, but the last couple times I used it, I haven’t taken the liner with me. The one time I had to close it up some, I wiped down the walls before I fell asleep and in the morning the condensation was there but it wasn’t too bad.

Yeah, I just saw the liner for the Double Rainbow. That's a great idea, too bad the Rainbow doesn't have an available liner.
