nice van! I have converted old Sprinter myself, 300k miles still going strong! Do you actually use Liqui Moly premix? I have used it back in 1998 when no one knew about it :)
Beautiful van! I'm still trying to figure out how they're getting so much clearance to have a bed that you can sit down on and space for the bikes. From what I gather the Sprinter high roof has floor to ceiling dimensions of 74 inches or roughly 1.90m, which is definitely not enough room.
