Yes, the awning canvas was made specially for us by Graham at Tent Valeting Services near to Bolton. I had an old alloy caravan awning frame (Graham can also supply poles), which luckily had steel joints, so was easy to alter to fit the Dormobile. I took the Dormobile and frame to Graham and left it with him. I told him I wanted in the traditional light green fabric to match the age of the vehicle and he already had it in stock. He recommended the plastic fabric for the roof as it will cope better with the fact that the door does rub on the roof and lets more light through. I also gave him a drawing with the design, and position of the zips. We had a long chat, including agreeing on the size of mudwalls (I had these made extra big to allow rocks to be placed on them. In the Sahara, you cannot use pegs, but sand on the mudwalls was enough to stop it blowing away in the sand storm) and then I left him to it. I collected it about a week later.
Here it is showing the awning in normal day mode. The side of rear awning attaches to the side awning, allowing us to stay dry/out of the sun. We have awning rails both sides, so can do this on either side.

There is a link to their website in the suppliers section of this forum.
Happy to show you it, if you pop across
