Auto-Sleeper Symbol 2018. The Auto-Sleeper Symbol has been the long-serving name in the van conversion world. This is a very well thought out vehicle that does not take up a lot of space. The layout with the fitted premium pack enhances both, looks and practicalities, ideal for anyone thinking of downsizing from a coach-built motorhome. Also, an ideal second vehicle for the family to use on short weekend breaks and long holiday journies. Ideal for those city centre tours and parking is easy.
