Not sure which one you saw exactly but there are a few awnings that are easier with one person. The Hannibal and Scipio awnings are roll out designs but a little difficult to get a hold of. I think So-Cal teardrops sells the Scipio. Not sure of an dealers in the US for Hannibal. The Eezi-Awn Swift is another option that is easy for one person. It's not a roll-out but it has two swing arms with a center support bar along with legs that drop down. You can get that one from Equipt.
Good deal on a used Scipio on Expo

I commented about using an arb vs a Chinese clone. The Chinese one being the better one. I don't have time right now but I'll try to get back this thread in a bit.
This is the link that I commented in. I think arb is using the better dual slot design now too. It's not something I would have thought of until I helped a camp neighbor set up his. I thought why do you need two people. Then I saw how it was built. http://www.toyota-4runner.org/5th-gen-t4rs/262131-sunseeker-2-5m-awning.html
Bingo, that was it. Thanks dude!
