We converted this van and lived in it on an epic road trip around Europe and Morocco for 8 months! It has:
. Solar panel and self charging leisure battery when driving for complete off grid capability.
. Fridge, Sink (with fresh and waste water tank), 2 hob cooker that is fuelled by propane that you fill up from petrol stations using 'autogas' (very cheap!), storage cupboards, LED lighting, socket for normal plug for charging phone, laptops etc, USB charging point
. Slide out double bed that becomes an L shaped sofa around a fold up table
. Fully insulated, roof vent to allow fresh air in at night.
. Can provide with 2 beginner surfboards (1 foam board, 1 mini mal) (on a if you damage or lose basis you replace) that can be strapped to ceiling.
