I do love my Tepui rugadized autana... I recently made a point of lowering it for ease of use. My only complaint about RTTs is waking up in the middle of the night to pee. That's when I hate that ladder... I am seriously considering an autohome or Alucab for the super duper uber fast setup and takedown... i find that the flying bricks still take a lot of time for setup and breakdown when you're doing one night and run, one more night, run....
Take a bottle up with you. Done some mountain climbing in the past and believe me it's really helpful!
Just don't confuse it with your drinking water!
