Here is my favorite vehicle. I am pretty proud of this since I helped design this - sort of a RV.
This is a custom build Mobile Command Center built on a Freightliner chassis. It is used at major incidents as well as communications. It has 10 fixed radios that can talk to or interconnect almost any agency. Multiple hand helds for marine, aircraft, you name it. Satellite phones, sat internet communications, and sat weather radar - everything we need to operate if all local infrastructure is down. It also has a 25 foot telescoping mast with antennas and a movable camera on top.
Here is the communications area up front. It has three work tables along with blackout curtains and a closing pocket door.
Here is the galley, the middle storage area and bathroom to my right, and the conference room in the back (or I can sleep back there). I can carry 60 gallons of diesel and have a 12KVA generator. I also have two 6 volt batteries for the accessories, two 6 volt batteries for the radios, and two 12 volt engine batteries. They charge from either the engine alternator or the two 60 amp redundant converters (powered off generator or shore power). It also has a 3KVA UPS for super clean power to the computers.
Oh - and dont forget the Incinolet toilet - no black tank to mess with!!
Anyway - that is it....hope you enjoyed....
