A vehicle fluid storage system, comprising:

• a frame assembly comprising a lower portion and an upper portion, the lower portion comprising a plurality of brackets configured to couple the frame assembly with a chassis of a vehicle,
• the upper portion comprising first and second upright frames, the first and second upright frames being disposed on opposite lateral sides of the frame assembly and each comprising a fuel pressure vessel support and an auxiliary fluid pressure vessel support, the auxiliary fluid pressure vessel support being spaced apart from the fuel pressure vessel support;
• a fuel pressure vessel coupled with the fuel pressure vessel support of the first upright frame and with the fuel pressure vessel support of the second upright frame, the fuel pressure vessel configured to be filled with a combustible gas fuel;
• an auxiliary fluid pressure vessel coupled with the auxiliary fluid pressure vessel support of the first upright frame and with the auxiliary fluid pressure vessel support of the second upright frame, the auxiliary fluid pressure vessel configured to be filled with an auxiliary fluid;
• and
• an auxiliary fluid manifold having a first end fluidly coupled with an internal volume of the auxiliary fluid pressure vessel and a second end fluidly coupled with an auxiliary fluid port to be coupled with a pneumatic or hydraulic system of the vehicle.
