Most of the Campervans sold here have the awning mounts on the side of the van, i've got a set of VW Candy White Aluminium mounts sitting in the shed waiting to go on for mine.
The bottom of the legs clip into the mount that is screwed in, so there is no marking of the van, if you look at the mount location, it's close to the fold in the door, that is quite strong and won't deflect.
There are two versions of the mount, a plastic one and a Aluminium version, i wanted mine colour coded.
