Police MCV

I'm working on reinforcing my law enforcement setup right now, and in doing so I came across a perfect application for the police MCV-- it's a mobile command unit run by the state transportation authority police. Unfortunately, though, the police MCV can only carry one person, and the real-world unit is a very large truck that carries a number of personnel. Any chance we could bump the capacity of the police MCV to 6 so it would be on par with the fire equivalent?
