The question of deadly force does not depend upon whether your property is in your own vehicle or a government-owned vehicle.
In general,
you are not justified in using deadly force for burglary of a vehicle.
There is an exception in the rule for "theft during nighttime", but then you have the burden to prove:
(3) he reasonably believes that:
(A) the land or property cannot be protected or recovered by any other means; or
(B) the use of force other than deadly force to protect or recover the land or property would expose the actor or another to a substantial risk of death or serious bodily injury.
Personally, there is nothing in my car worth the $10,000 or so I would need to pay an attorney
just to start on my case. Regardless of my legal justification, I have made an economic decision that I am not going to shoot someone over my car or its possessions.
Now, put me or my loved one inside the car, and turn it into robbery instead of burglary of a vehicle, and that is a different story.
Glad I could help.
