Took a bit of time out today to make a set of roof supports. I had some on the old van and used them in strong wind conditions. At times the roof would come down so I used these supports for a bit of extra strength. I copied the idea off another down under member and used 15mm pvc pipe with 22mm rubber plugs from Bunnnings. I also went around each leg half a dozen times with electrical tape to keep the rubber plugs tight on the ends. All up less than $10 from Bunnings. I also have a couple of adjustable supports but think these are just a bit easier to attach.
