We had the Dometic electric awning our Escape. It can be deployed out to any point and then stopped. The problem we had with ours was it would not tilt in the rain so water would pool in the middle and would sag the fabric. It was suppose to have a dump feature but we never saw it work. There were a few that bent the arms from water weight of pooling water. Escape finally put out a notice to only deploy it 3 feet in the rain because at that point the arms would bow up the middle and allow the water to run off. The wind sensor did work but it had to shake for 6 seconds before it would retract. If it was a quick guest of wind it could be a problem. We probably used it more then we do the manual awning but never left it out unless we were siting under it. I am curios to see how they hold up on the Oliver's.
My opinion of the new awning is I would get the electric because it does have the retract feature that the manual does not. The electric also has a LED light strip. The new manual awning is the same as the electric and is self supporting and does not have support arms like our older ones do.
