I like the ones where the ladder is completely outside the footprint of the tent as opposed to underneath the tent and protected by it . Just seems to me like a waste of "tent space" up top for the ladder, and a waste of sheltered space down below. Twice I've sought refuge under a RTT during adverse weather (horizontal rain/snow awfulness) and it was kinda neat, being inside those changing room walls. But never so bad that I couldn't have made it up the stairs to go to bed.
Have you read that article that Kurt Williams wrote on these? I thought he did a great job explaining the +'s and -'s of RTT's in general, and some of the key differences. Pretty sure it's on Expo, maybe his site as well... lmk if you want help finding it.
