Sorry I missed this posting or I would have responded earlier. Yes! Get awning locks - even if you've got an aluminum wrapped awning. I've had a good, aluminum wrapped A&E awning on my Allegro Class A since 2000 and I've always felt that I didn't need anything else to hold the awning in place. Well, I (almost) found out the hard way that that's not correct.
While driving through El Centro, CA last February, in very strong winds, I saw (in my rear view mirror), the forward awning upright separate from the wall about six inches and then slam back onto the wall. A strong gust of wind had overpowered the latching mechanism at the top of the upright - something I thought would never happen. I usually don't drive in such winds (it's no fun), but I was late for a family get-together. I couldn't get stopped fast enough. I made a roadside fix to secure both uprights and later installed some stronger, easily-removable straps.
FWIW.
(By the way, I don't have a center brace. Such braces may prevent unintentional roll-outs - I don't know)
