Flex Dream has introduced the MONOBOX:Di-seat custom conversion for the Mitsubishi Delica D:5, enabling the interior to be adapted for overnight stays. The second-row seats are replaced with a module offering three configurations: forward-facing, rear-facing, and a full flat bed measuring approximately 1100×1680 mm. Because the seating capacity changes from 8 to 7, a registration modification is required. The displayed vehicle is priced at 8,346,960 yen including options, with a base price of 5,698,000 yen.
