|The XM 520 E1 cargo version
went into production as the M 520.
The one in the picture with the small crane in the back is known as the
The engine was a multi fuel D333 by Caterpillar later models used the pure diesel D333C that produced 192 hp at 2200 rpm that gave the Goer a road speed up to 50 km/h and that was to much for a vehicle without suspension 30 km/h was possible without falling apart of vehicle and driver.
The Goers are amphibious and can do 3 to 10 km/h in calm water by the turning of the wheels. There was no extra water propulsion.

|The M 559 tanker can carry
105 gallons (450 ltr) of fuel in it's 2 tanks.
The Goers are 4 wheel drive in the lowest 2 gears, the rear wheels
being driven by electric motors.
In the high 4 of the 6 gears only the front wheels are driven. The gearbox is a power shift type. The cargo and the tanker did not carry spare tires.
|The mechanics of the XM 553
wrecker are the same as the M 520 and M 559.
The extra 2 tons come from the 2 spare wheels, the crane, the rear
winch and the stabilizing jacks.
crane = 10 tons

This Goer carries a Nike-Hercule missile for a test.
That was around 1965.
I do not think that it was amphibious while carrying that missile. :-)
