Aesthetics wise the combination of the EV6 and that carvan look amazing!
As to expreinces I would recommend checking out Andrew Ditton on youtube as he is towing with his EV6 and gives good details of how its going, range etc - IIRC he was getting between 100 miles and 150 miles but found things like V2L extremely useful when wild camping (powering the caravn overnight, cooking a meal making a coffee etc was perfectly within its capability)
