Could trucker quickly separate tractor from trailer for this refrigerator(?) fire?

This is an incorrect statement. We have some 2013 Peterbilts and Freightliners, none of which have an in-cab 5th wheel release button.

 

I can drop and be out from under a trailer in about 90 seconds flat.
Fire takes a bit to totally engulf a truck.

 

In reality usually when the truck catches on fire I mean a real fire the extinguisher is kinda a joke might help on realativly small fires but by the time your trailer catches your screwed

 

And the thing about dolling down the landing gear screw it if I'm gonna save my tractor I will pop my lines and pull the pin and hell with it if the trailer drops can do that in under 5 seconds
