Just a heads up for anyone who has one of the Kings awnings. Like most (all?) of these types of awnings, the main two aluminium sections (the backing plate which attaches to the brackets, and the channels which hold the spreader poles) are held together with aluminium rivets. These rivets appear to be pretty soft, and they are prone to shearing off after a while if you are driving rough tracks and/or corrugated roads.
It's a real good idea to drill them out and replace them with small bolts with nylock nuts before they fail, (rather than after it falls off your vehicle).
Apart from that, I've found the one I have to be quite well made and fit for purpose.
(PS. Mine didn't actually fall off, but after a high country trip nearly half the rivets had sheared off. I have heard of a couple of people who did have the whole awning part company with the vehicle.)
