Hi,
So after searching the web for a long time now finding something equivalent to Mobile Air, in Sweden but turn up empty.
So what i would suggest was adding a truck with demountable body which is much more common here in Sweden, the way i would say it could work would be you buy a truck and when you open the truck
you would have an Extension tab as in buildings with option to buy loads/bodys to the truck, like Mobile Air, Hazmat, Rescue, Water-tank.

With one load on going on calls with that load should be instant but if you want to change load it should take a few minutes before it is available to go to the call.
Would be one vehicle covering multiple areas but having to wait a while to switch to the correct load.
Im not sure if this would be doable or anything that would be of interest, not even sure if and how many other countries use systems like this.
Anyway just a suggestion that would be nice to see for us Swedes at least
