M106 Trailer, Tank: Water, 1 1/2 Ton, 2-Wheel, 400 Gallon
The M106 water trailers are based on the M102 Chassis, Trailer, used to transport, store and distribute drinking water in the field. The M106 and M106A1 water trailers were introduced in the 1950s, equipped with 11:00x20 tires to match the M34 and M135 2 1/2 ton cargo trucks. With the same tires, the combination truck and trailer would ride at the same height.
The elliptic cross-section aluminium tank has a capacity of 400 US gallons (1,514 L). The trailer has a hand pump and a 25 foot (7.62 M) suction hose for filling. Fenders and extensions provide table surfaces when serving water.
The M106 trailer may be completely submerged when fording when towed by a towing vehicle with an air supply. The M106A1 has a cover plate over the piping between the two welded metal tap boxes at the front of the tank. The M106A2 employs two hydraulic wheel cylinders for each wheel service brake. The M106 trailer has a rear support leg while the M106A1 and M106A2 do not have a support leg.
The manuals for the M106 water trailer are TM 9-875B (October 1951), TM 9-8226 (April 1955) and ORD 7-8 SNL G-754 (1954). These manuals cover all the 1 1/2 ton two wheel trailers of the time. The manuals were replaced by TM 9-2330-213-14&P but the replacement manual did not include the then obsolete M102 and M106.
