A complete additive transport and mixing system is carried on a single vehicle. A collection of liquid additive containers, a collection of metering devices, and a mixing system are all mounted on the vehicle, as is a dry additive metering device. A selected liquid additive container can be selectively and changeably connected to a selected liquid additive metering device, and a selected liquid additive metering device can be selectably and changeably connected to a selected input into the mixing system. The metering of the liquid additives is monitored and a concentration display given so that the metering devices can be manually controlled to obtain an actual concentration equal to a desired concentration. A display indicating a desired setting for the dry additive metering device is also given so that the dry additive metering device can be manually controlled to allow a suitable amount of the dry additive to be added into the mixing system to obtain a desired concentration of the dry additive.
