So I'm taking a lunch break at the ski resort, and parked next to me is this behemoth of a Mercedes Sprinter van. It looks like a really comfy rig. Space heater, room to stand, its probably got a queen mattress and a hot tub in there too.
However, I would argue that Sprinter vans are still minimalist. Everybody's threshold for minimum survivability is different. And Sprinter van people have decided that their minimum includes a Keurig and dishwasher.
