The 144" Sprinter is the sweet spot of the van world: it parks in a normal space, it fits most garages at standard roof, and it still holds a crosswise bed if you plan the walls properly. The trade-off is that length-critical parts are not interchangeable with a 170.

Everything on this page is cut, drilled or moulded specifically for the 144" wheelbase - roof racks that match the roof-rib spacing, wall framing kits that terminate at the right rib, and capsule and pocket-sleeper trim sized to the 144 rear quarter opening.

Sleeping across a 144 is the classic problem; pocket sleepers are the standard answer. For everything that fits any Sprinter regardless of length, see Mercedes Sprinter Parts.
