My old motorhome had a manual Colorado awning and that thing was tough, I would leave it out even in storms. It would anchor to the ground and it didn't move. The only time I ever put it in was during a huge storm on South Padre Island, I think it could have handled it but better safe than sorry. I swear that thing was the chuck Norris of awnings!!
For the last year we have had the power scissor awning that comes on the wildwoods and we leave it in unless we are going to be under it. At the most we might leave it out a foot or two to keep the rain off of the stuff we tuck under the camper while it rains.
