We just purchased a 1990 Layton with a pull-out awning. It opens great... yada yada - here's the dumb part: How does it retract? My husband rolled it up by hand, but isn't it supposed to go back by itself? We saw a turny-latch thing that mentions (words to this affect) roll out and roll back, but the awning never moved to go back into it's original position until he cranked the entire thing by hand. Any help will be greatly appreciated (even if I am embarrased!). Thanks!
