I see. Very nice. As a unit we decided against the Dodge Sprint as it is too tall and cannot fit into parking decks.
We use an F-350 Van, which is one of the best overall CSI units you could want. One sliding door, and the shelves ONLY on one side for other items, like haz-mat gear bags, and tools, i.e. sledge hammers and saw-zalls. The lack of windows on some of the TC models is great for security reasons when parked and the partition between the front and rear areas.
One thing to remember is inverters for plugging in lights and other items at scenes.
I would be interested in seeing how this pans out with your contractor. Are you advising your area has a " co-operative Govt. bid"? Please explain that for me.
One last thing is the TC available with only one sliding door?
