Auto-Sleepers is our longest-established volume converter of motorcaravans. As with many marques, it started off as a DIY exercise. Former steel company director Calverley Trevelyan converted a Morris J2 to take his family on a touring holiday in France.

The conversion featured a canvas rear annexe tent that folded upright for travel. Included in that family foray to foreign fields were his sons – Anthony and Charles – who between them have had a major influence on the esteem in which the marque has been held over the years.

On returning home, Calverley decided to sell the converted Morris J2 to Henlys of Bristol. They were so impressed, they ordered five more, this time on the Austin version. As soon as the five had been completed, they ordered another 12.

This couldn’t be fulfilled as a DIY project, so Calverley joined forces with local builder Bob Halling, bought an old building in Manchester for £99, and Auto-Sleepers began production shortly afterwards. They quickly ran out of room and relocated to the Cotswolds, where they remain today. Auto-Sleepers’ own-design solid-sided parallelogram-lift elevating-roof soon became a highly regarded feature on all Auto-Sleeper campervans.
