the van is situated permanently on the same site Getting decking down so that awning will be on dry ground. but am not sure how to fix to decking area.
Will have a look for the screw-eyes, that you have suggestions many thanks
If there are spaces between the decking planks I would make some upside down ' J ' hooks , or roofing hooks, slot these between the planks , turn 90 degrees, that's what I did to a neighbours gazeebo.
Ive just done the same thing (decking then placed awning on top) I used screw in cable routers works a treat with no sharp edges

On our seasonal site all of the vans have decking due to being on a hill. The vast majority of people have used j hooks to secure their awnings to the decking.
