Family with 2 beds. Only recommendable for the longest and highest Sprinter version (L3H3)
Lounge area with all storage inside the car and therefore no garage. Lounge needs to be converted into the bed for the night.
Fixed bed with big garage below. The overhead cabinets are not recommended to be able to lean against the wall (at least one side) and also have more space.
Variations of the Lounge area with partially garage utility.
Some more examples from the different layouts.
