Not much help I'm afraid, but our Cabanon Atlantis DL didn't have instructions from new. Only main thing we had was a relatively thin handbook with diagram of poles, but the dealer spent an hour or so on demo when we collected.
I've just checked the Cabanon website and there's not much help on there either - see this link here.
I did find though that they were helpful with a query via email, so perhaps drop then a line and they'll arrange for whatever instructions are available, to be supplied. You can email them via the link I've given above.
Many thanks for your reply. We will try the link and email them.We did manage to get the trailer tent up but it took us about 2 hours plus and 1 pole spare!
Glad we wasnt doing it on a campsite cause everyone watching would be rollling around on the floor in floods of laughter!!!!!!
My brother has a Cabanon Mistral which they've used half a dozen times. I think it takes them about two hours to put it all together. Don't know about the spare pole though - although if you have the extra metre extension with wardrobe compartment it could be the hanging rail?
