Public building? I'm not sure what you mean by that. Aren't most buildings "public??" But there are no laws prohibiting concealed carry in public buildings. We can't carry in court houses, police stations, polling places, gov't meeting facilities, schools, post office, airports. That's about it.
As a concealed carry owner. This is part of the training, at least it is in my state, and known places it is unlawful to carry:
According to 40 USCS § 3301 (5) [TITLE 40. Public Buildings, Property, and Works; Subtitle II. Public Buildings and Works; Part A. General; Chapter 33. Acquisition, Construction, and Alteration], the term “public building”

I have a safe I can use in my vehicle if needed. But leaving it temporarily locked up in a vehicle safe (while I run into a prohibited place, for example) doesn't make it a "truck gun."
No, but if I know I'm going to a high theft area, I'm taking a truck gun and not a nice gun. Though a vehicle pistol safe is an excellent deterrent, it's not going to keep your weapon 100% safe if someone wants to steal it. Also, there are vehicles where bolted down pistol safes are not possible or would damage the vehicle. Put it this way, I don't keep my best guns in my biometric safe by my bed. Why, because the safe could be stolen. Guns in home safes can be easily stolen too. At best, it will slow them down long enough to either be a deterrent or move them on to easier stolen items.
To me, "truck gun" implies something that is LEFT in the "truck." Something that is not carried concealed. Just like a "home defense gun" is left in the home, not carried.
That's one definition. It can mean different things to different people. I feel it is either a supplemental weapon or one that, if it gets stolen, you are not out a ton of money. Not just my definition but it has become synonymous with the term "truck gun." Yes, as gun owners, we have a responsibility to keep the weapons out of criminal hands. However, if you are a realist, even your best efforts will not always work, hence, the truck gun
