If you really rush, and work as a team, you can put one up in less than 5 mins.  Working very leasurely and making sure that everything is as it should be, 10 minutes is very easy.  It's not that big a job after you have the unit leveled.  You can put it up in a rain and still keep it (if not you!) dry inside.  Neat rig!  We have an older version of the 2720 (m0del 23) and love it.
