Design parameters.
The third row seats are often used to haul kids or the cargo area is used to haul bulky items and the Cruiser is only used in "expedition mode" several times a year so the "system" will be easily installed or removed. The drawers do not need to be a sleeping platform. The drawers will be crates that can be unloaded at camp or easily unloaded at home for storage. Using leftover plywood that was cluttering the garage, the cost will be about a hundred bucks. Add $30 bucks to that if you need to buy an additional sheet.
