View shop64 of the shops we list build on the Mercedes-Benz Sprinter, across 18 states. Plenty of builders work on one platform only, so this is a genuinely different shortlist from the other two.
Published build costs among these shops run from about $5k to $300k for the conversion alone. The Sprinter itself is a separate purchase unless the builder sources it, and the chassis price differs sharply between the three platforms, which is worth factoring in before the build quote.
The default premium platform. Factory 4x4/AWD, tall interior, and the only chassis with a formal Mercedes upfitter program.
The chassis narrows your builder shortlist more than anything else does, so it is worth settling early.
