I have two of them. Excellent tents. Ignore all the complaints about complexity and nightmare if anything breaks. Its a very simple system and I've only ever had one issue where a knot in one of the cables came undone - easy fix. I've used them from Canada to Baja and all over the western states.
Are they as simple as a clamshell - no but they make up for that with room and the ability top keep your pillows/blankets inside.
