Just to add to this resource as these days with everyone using Facebook we are in danger of new material being lost in one endless post. I've added this information on the FB page but that will be lost forever very quickly.
here is my solution to fitting an awning on a troll from 2016, this vango kela lll LOW has a fitting range of 180 to 210 and is designed as a VW transporter type drive away awning. The photos show the very first attempt and it was pretty simple. Materials of construction appear very robust and it has a 3 year warranty.
The awning fitting kit is shown as supplied here, it needs cutting to 2.5 M long and has since been done, in the photos you can see it is way too long and only needs to be the length of the awning bead attached to the vango kela lll
Additional, i will position it 2 inches further back next time to clear the external locker and ill still have very good door opening access beyond 90 degrees. it will of course still cross the window but thats not a big deal as far as I'm concerned although to some I can see it would be.
Additional additional, moderator please add images to the awnings photo page for ref.
Any questions just ask.
