Isabella out of Denmark makes what looks to be a spectacular "awning" for the Euro T@B 400. There is a dealer in the UK that ships these out of the country, but they are pricey (about $2000). http://www.broadlane.co.uk/awnings/isabella/isabella-tb-l400-awning-2017
http://www.isabella.net/int/special-models What Isabella calls an awning is what we call a tent. Their "awning" is called a sun canopy. These are very sturdy units with substantial poles and cross braces. I am not sure how well they fit US T@Bs. A UK caravan site I found mentioned "fits UK/EU model T@B only".
