I finally got around to a new command vehicle for the BCLES. I think that it is possible that this is a real truck design, although I am not entirely sure if it is. Instead of a large bus or truck, this smaller, more maneuverable truck is helpful in tighter city spaces.
The design should seem familiar, as the cab (although slightly modified) and the chassis come from the City Fire Pumper's redesign (http://www.moc-pages.com/moc.php/431791). The back is also very similar although the rear door is slightly altered to better fit the new truck. It also has a large front fender, as it looks cool in my opinion, and is an optional feature on police vehicles.
Here are two possible real trucks that sort of match.
