We also have the Apex awnings on our rig. As far as I can determine there is no channel in the awning to hang anything from. Remember that the roller tube is attached to the MH and not the extended framework.
I'll go look at the service manual again though.
Nope, doesn't appear to be much of any way to do it unless you extended the awning, turned off the autoretract, got a ladder and hung it from the fascia. I don't think it's strong enough to take that and survive a wind either.
I need to order a new dual awning control box, ours powers on, goes through the check cycle then may either stay on or turn itself off. I also found something leaking from it and it smells like burned wiring. Don't really like spending $466 right now though!
