Not sure what the bolded has to do with anything. I mean, if you're in a cabin and need to get to your car in a rush wouldn't the same apply?
RTTs are a funny topic. Some people the very thought offends them, some people get extremely upset about what other people spend their money on, some people are more than willing to condemn them without ever spending a night in one.
I have an Alu-Cab 3.0. It sleeps my wife and I comfortably, sets up and breaks down very quickly, and stays clean inside because we aren't tracking stuff into it like always happens with a ground tent.
We seldom stay in the same place for more than one night so the lack of portability, which with this tent is almost nonexistent anyway isn't a drawback for us.
The only time I've slept as comfortably in a ground tent as in my RTT was on a cot, and that's just another piece of equipment I would have to load.
It's one of those pieces of equipment that certainly isn't for everybody or every situation, but they also don't deserve the ridiculous criticisms about them people often make. Recent discussion someone said that if you were in the desert and there was a flash flood you would be screwed with an RTT. I could literally be moving as quickly as I could pull the ladder and throw it in the car, get in the car and get it started. With most of the wedge style tents as long as there weren't any low trees you could drive off without even closing it.
