Volkswagen Caddy California.
What to Check Before Buying.

The Volkswagen Caddy California turns a compact van into a weekend camper with pop-up roof, fold-out bed, and kitchen unit. It offers the practicality of a Caddy van with genuine camping credentials, appealing to buyers who want something more usable day-to-day than a full-sized motorhome. As with any camper conversion, you need to check both the mechanical condition of the base vehicle and the state of the camping equipment. Electrical systems, roof mechanisms, and water fittings all need careful inspection alongside the usual van components.
