1. A mobile thick matter pump for conveying thick matter, the mobile thick matter pump comprising:
a trailer chassis having a longitudinal center plane;
a pump unit arranged on the trailer chassis and comprising a two-cylinder piston pump and a water box,
the two-cylinder piston pump comprising a first cylinder, a first delivery piston, a second cylinder, and a second delivery piston,
the water box including a cover; and
a drive motor arranged on the trailer chassis and configured to drive the pump unit to convey thick matter,
wherein the pump unit is arranged eccentrically on the trailer chassis such that the pump unit is laterally offset in a first direction relative to the longitudinal center plane of the trailer chassis,
wherein the drive motor is arranged eccentrically on the trailer chassis such that the drive motor is laterally offset relative to the longitudinal center plane in a second direction opposite to the first direction,
wherein the water box is accessible from above for replacing the first and second delivery pistons via a free space formed above the water box as a result of the drive motor being laterally offset,
wherein the free space above the water box allows the cover to be opened.
