This is something that you don't want just anybody to do for you. We at ASE have equipped many command post vehicles whether it is just a pull behind trailer, a box truck or van, armour vehicles, and even motor home style vehicles.
We can add electrical outlets, internal lights, bypass wiring for the generators, phone jacks, power inverters, chargers, control panels, shelving, cabinets, video systems, etc and we do all the regular outside stuff like LED lights, strobe lights, scene lights, graphics, external power panels, etc.
Just give us a call and let us go over all the options available to see what matches up with your needs.
