Some trucks are automated, others have drivers, some have advanced ignitions that require the wageslave driver, some require constant wifi... you might have to just see what you get =P
As for theft, depending on what you pick to go after I'll give you a security rating, which will need to be beaten with a hardware roll (relevant tools like a maglock sequencer will aid this) and an encryption level and fire wall level that will need to be beaten the usual way, followed by taking it off the gridguide, etc , then you just need to do the stuff in Vehicle Anonymity and Vehicle Security to avoid being caught with the vehicle.
