It kind of depends the MB/Dodge Sprinter has a 5 banger Diesel, that'd probably do it.

Also begs the question, what's the strongest 6 in production today?

BTW the Pheonix is slated to replace the currant 6 cyl for now, not every engine,
Could you see someone trying to pull a fifth wheel trailer with a six banger pickup?
