Spotted: Toyota Land Cruiser Troopy - unique roof conversion

Overland vehicle modification is big business. Just look at the number of 4x4 garages, retail outlets and online sellers.  Even with all of these professional outfitters offering similiar products and services, independent overlanders always tend to find a unique way of modifying their vehicle.  Take for example this Land Cruiser
