Carefree of Colorado awnings

Thanks to wannavolunteerFT. I have been trying to convince my wife that we should consider going to the crank setup. Her concern is how long and how many turns it would take to do it by hand? I suggested maybe to modify a crank to work with a power drill. Has anyone tried that? If I convert to crank will that replace and eliminate the springs altogether? We have to decide if we replace the whole assembly or just cranks and fabric. The front does not release freely and so the fabric has started to separate from the aluminum weatherguard. Being a 20 foot awning it won't be fun to do twice so I am using the great advice and experience here to make the right decision the first time. Since I changed coaches I have also updated my username in case somebody noticed a change.
