Hino, Toyota's truck subsidiary, are now selling a Hybrid medium size truck. These are large enough to carry a containerized shelter for a Mobile Command Center, as used by the police, fire and other emergency services. Use of a hybrid vehicle has been noted saving having to install a separate generator in the truck to power lights, computers and air conditioning.
The Hino Hybrid truck has a 23kW generator and 273 volt 6.5Ah battery. This would be enough for a small containerized shelter the size of a 20 foot ISO shipping container. These can be expandable.
An example of an Australian mobile command center on a truck the size of the Hino Hybrid is the Victorian Metropolitan Ambulance Service mobile command and communications vehicle. The Fire & Emergency Services Authority of Western Australia Incident Control Vehicle is based on a smaller bus chassis.
A large range of commercial vehicles are used for mobile command centers, from ones based on SUVs, up to articulated semitrailers. As an example the Mobile Command Center (MCC), of the US Joint Force Headquarters National Capital Region (JFHQ-NCR) is on a 41 foot semi-trailer.
The same technology is used for mobile classrooms, PR displays and outside broadcast units.
