Yea Frank is correct, it is known as The Sleeper as on 365 camping. However that website is well out of date now.
The company that built it has now sold The Sleeper on to AV Innovative and the price has increased somewhat.
The Sleeper weighs only 150kg and can carry 350kg of camping kit, then provides a warm and comfy bedroom for us when we arrive at our destination
Here is a pic from our first trip, before we had started to "dress" the trailer the way we wanted it.
Then more recently at a show with the Golf too
Glad you approve. For more info on Teardrops please feel free to visit and maybe join The Teardrop Club of Great Britain. Lots of info on there and lots of very unique trailers too
