Awning

As you’ve had no replies I suggest that there are few with your model and even less using an inflatable awning on it. You may be best requesting advice from or even taking the van to a specialist awning dealer. Glossop Awnings are, in my experience, very helpful. Best of luck finding the solution.

Sometimes worth checking to see if there is a Facebook group dedicated to your make of motorhome where you will find more detailed information. As Micky suggests there are probably not enough posters on here with your model and even if there were a handful is likely that quite a few wouldn't actually use an awning beyond the wind out variety.
