Dump truck specifications vary greatly- too much so for a "one size fits all" type of answer. A better idea of what type of dump truck, how many cubic yards the bed can hold, etc would be needed here.
Dump trucks typically don't haul liquid commodities, unless you're thinking of snow removal operations where they'll be outfitted with prewet or calcium chloride tanks. Even with that in mind, you need to remember that there are many different sizes of dump truck out there. 15 cubic yards is "typical" for a tandem axle dump truck.
