The quality of electric awnings has improved dramatically over the last few years. Ours works flawlessly every time and takes about 20 seconds to deploy or retrieve by simply holding the button (which can be done from in side the coach. While I don't have much faith in or the need for, the models that have the so called "auto close" feature which will roll it in if the wind reaches the preset threshold I will never be without an electric awning again.
They also serve to tell you a lot about any RV you may be considering. Given the relatively small cost differential between the old manuals and the new electrics you have to assume a new RV with a manual awning probably is on the entry level side of the scale (and wonder what else they went cheap on that might not be showing).
