Van Cover Venting

An idea, meant post this up a while back.
32mm plumbing waste fittings. Front and rear, stops the cover sagging on the roof.

 

Could also work as the basis for a solar shower

 

I have thought sometimes that something like that but extended out as a frame down the sides would also be good to stop the cover keeping the sides damp. Nice idea.

Or an inflatable tubes style awning/cover that happens to be in the shape of a bus , but a bit bigger so you can put it over the bus then blow up the tubes and it bows away from the body , but is somehow steadied to the roof gutter so it doesnt keep rubbing or slapping in the wind..
