I might give this another go. The key points that are wrong are:- 1, The attachment system grabs and seizes, being Ally and needs too precise a fit. 2, The leg attachment points in the Awning area are too close to the middle so in effect take almost all the weight. 3, The amount of room left for the truck to leave and return is too narrow. So, I could use the longer outriggers that go in the awning on the side in the photo, and the shorter ones in the awning with an extension piece to put the legs in the right place. Revisit the attachment system with a redesign. I could then Guy it down with ratchet straps in the corners. Trouble is taking all the gear to do it.
