using it in a car or storing it there is not a consideration.

Not an issue as long as you dont need 'on-the-road' net.

Power is a consideration. You need power that will not jump around
--regulated. maybe a 12v battery with a way to convert to the needed ac
or dc. IIRC some micro-atx or similar use dc power bricks.

This temerature is an issue if a computer (or more to the point an LCD)
where to be exposed for a reasonbly long time. I'd have to check the
toughbook specs to see where they work. I dont see using a CRT as they
are too heavy, big and use too much power. Unless you want a 9" green
screen?

Condensation is the most pressing. A ruggedized laptop might address
this.

I would guess that the laptop was connected to a phone line or power
line. You'd need some protection for the telephone line even in the
city. And you should almost use a UPS to guard aginst power spikes and
power loss.

toughbook ->phone surge protector->phone
          -> regulated power->power

or

shuttle pc ->phone surge protector->phone 
           ->converter->12v battery
lcd monitor->converter->12 v battery
