The design is interesting, but I'm hugely cynical about anything that is nylon; it't tent fabric and will die relatively quickly from a lot of UV exposure.
For example, check out this ridiculously expensive trailer TENT. It's a TENT, on a trailer:

The nice thing about a teardrop (in my limited experience in sleeping in one when we rented a Little Guy over a long weekend) is that it's very quiet inside. Same with sleeping in our van. Super restful and get a great night's sleep.
When we used our pop-up trailer, you can hear every little sound and it's not very restful at all.
