Of the KS 25 tender for a payload of 4.5 tons, later known as the large fire-fighting crew vehicle (GLG) and finally as the LF 25, only 3,700 units were built. Of this total, 2,066 came from Mannheim and Gaggenau. Initially, Daimler-Benz also used the MB L 3750 chassis with 100 hp diesel engine, later to change exclusively to the L 4500 S chassis with 112 hp six-cylinder OM 67/4 diesel engine. The pump on this vehicle delivered 2,500 liters of water per minute up to a height of 80 meters. The vehicle itself was equipped with a 1,500 liter tank, and its superstructures were supplied by external fire-fighting equipment specialists.
