one other downside to a RTT: unless you have a heated garage or shop (I have neither), a RTT can mean extra down-time after a wet trip. The past two trips I've been on, the condensation from our breathing has left ice crystals on the inside and outside of the tent. This means I have to set up the tent again when I get home (no different from a regular tent.) The real bummer is when it's below freezing outside, so even when I re-deploy the tent, the ice doesn't melt, and I hate to have potential water sitting in my tent. So here's the downside: you can't just take the tent into your house to air out/dry, and when you do air it out and dry it, your vehicle is out of comission. If I have to run to the store, I can't just pitch the tent and run to the store while it dries out. Not a deal-breaker for me, but definitely something I didn't consider before today.
