Mercedes-Benz LAF – medium-duty L-range chassis as the base for fire and municipal service: six-cylinder engines of 4.6 to 6.0 litres, 7.5 to 11 tonnes gross weight
This page gathers Mercedes-Benz vehicles of the classic L range, whose three-digit type designations such as L 911, L 1113 and L 710 shaped the maker's medium-duty truck building for decades. These chassis were among the most widespread bases for municipal and fire-service bodies in Germany and much of Europe; the designation LF16/4200 in the register refers to a pumping appliance of the kind typically built on such chassis. The letter B in designations such as 1113B marks a version with a reduction gearbox for off-road use.

The register lists 11 versions, all with six-cylinder engines of 4,580 to 5,955 cm³. Unladen weights range from 4,847 to 9,412 kg, gross weights from 7,490 to 11,000 kg, lengths from 5,990 to 8,950 mm and widths from 2,300 to 2,500 mm.
For decades the L chassis formed the backbone of Germany's fire services and municipal fleets, as Mercedes-Benz offered an especially dense service network and long spare-parts availability for them; many of the pumping appliances built on them consequently stayed in service for decades.
When buying a used chassis of this type, what matters is the condition of the engine and injection pump, the clutch and gearbox, and the frame and brake system; on vehicles with a fire-service body, also the condition of the pump, tank and body electrics. Rust on the frame, running boards and cab floor is common on these older model years; parts for chassis and engine are available through Mercedes-Benz specialists.
