<p>The caravan conversion system for a tractor lorry has guide rails on the lorry, with the height control and castors under the caravan body to slide onto the lorry. With the rails dropped back the caravan is automatically secured on the chassis. Whendropped, the caravan body is supported on extending struts. The caravan can be collapsible and may be replaced by other fittings to change the function of the lorry. The caravan comprises only the essential body and does not require any chassis or drawbar.</p> |
