So I FINALLY got a chance to spend a few nights in this bad boy. Impressions so far?
Mattress: Very comfortable, compared to previous tents. The structure of this tent is memory foam over dense foam, with an aluminum spine under that, so no actual hard bottom. This gives a very supple, yet leaning towards firm, sleep surface. To my mind - about as good as it gets.
Venting: The two nights I spent were cold (-3 Celsius, which when winter camping is good, but it was still summer damnit!). I made the mistake of completely zipping it tight the first night, and even though there are two decent triangle vents, it wasn't enough. Woke up to heavy moisture over almost every tent surface. And this was a solo trip. My bad. The fabric is water tight, but this comes at a cost - breathability. Second night saw every window unzipped just a little, and no issues with dampness the next morn. Lesson learned.
Setup: Once the cover is removed (I put a roof basket right in front of the tent, so cover rolls right into it), setup is as fast as advertised. Put telescoping ladder in situ. Raise first pole, lock in place. Second pole raises it the rest of the way. Switch sides, erect the door-awning pole, and you're done. (Yes, I think I just used the word "erect in the same paragraph where I described pitching a tent - call me thorough).

Further details - shoe bags are a nice touch, and will be very handy when there are two of us, with even less room inside. The four way sail tracks are super handy for attaching all kinds of things underneath, and my ARB awning goes on in under ten seconds. Lovely. The lower profile of this tent affects driving a lot less than the quadruple pizza box stack associated with other RTT's I've had. But forget putting it on your Chevy Sonic. You need a lot more roofline than the sandwich style tent does. Although it would be handy to hide behind if you actually are camping with a Chevy Sonic. Oh I kid!!
As an added bonus, after leaving it on for my commute the last few weeks, my wife helped me take it off the roof last night. She's a good 7 inches and 60 pounds less than me, and she was able to hold one side. So this thing is not a featherweight, but manageable with two adults.
