This is an option I had installed when I purchased a new car at a Toyota dealership. It's for a 200 series Hiace wide. The height of the bed can be adjusted, and you can raise each side individually, making it easy to access items underneath. A double-sized futon can be laid out with room to spare. I've used it for 3 years, and while there's some wear and tear, there are no noticeable scratches or stains. The metal fittings are made of stainless steel, so they are rust-resistant. If purchased new, it would cost nearly 300,000 yen, so I think it's a good deal. I'm open to some price negotiation, but... I can't offer excessive discounts.
