Can multiple liquids be stored in a single liquid cargo bay? For example, can a fuel transport with a single bay hold a combination of petrochemicals and hydrogen, or can it only hold one at a time? Could a vehicle with sprayers hold flame-dousing (the forum does not like me using the actual name due to the Scunthorpe problem) foam, water, and coolant in one bay?
Transport bays may be found on page 239 of the sixth printing of TechManual.
