The Holidays in Sylvania theme has different sets, and now includes The Caravan. You can get the caravan with the car or without.

The roof folds apart allowing access to the inside of the caravan, where thee is seating, a foldaway bed and even a toilet.

There are loads of accessories included as well (over 30 pieces the box helpfully screams), so your little bunny friends can have a lovely relaxing caravan holiday.
