Just posting this because of the awning out thread, a telescoping ladder will not work for manually retracting it. I bought one last year and keep it in my bumper after removing the red strap.
It is not high enough or sturdy enough to get onto my roof(my camper has a ladder) but has come in handy getting to the top of my slide outs. I have spent a fair amount of time on it and felt comfortable.
Got mine from Amazon but they appear out of stock. Supposedly available elsewhere online.
