As concerns the original post, the Castle Doctrine (as already pointed out) has nothing to do with possession of a handgun.
In the event a person (NON-CHL) wanted to carry a handgun, it would have to fall under the traveling law (still on the books) IF that person were NOT in a motor vehicle. Or... any of the other laws that pertain to legal activities, hunting, target shooting, directly en-route to certain places, etc..
If you are in a motor vehicle (under your control..and you are not otherwise prohibited), then you would be covered by the Motorist Protection Act.
"Motorist Protection Act" (HB 1815).
Replacement for the “Traveling” Law Passed in 2005HB 1815 by Rep. Carl Isett (R-Lubbock)/Senator Juan “Chuy” Hinojosa (D-
McAllen). Now called the Motorists Protection Act.
For years, Texas law provided for a defense to prosecution against a charge of carrying a concealed handgun without a permit if the person was
“traveling.” However, “traveling” was never defined in law. In 2005, the Texas Legislature passed a bill establishing that a person is presumed to be
traveling if he or she is in a private motor vehicle, is not engaged in criminal activity, is not prohibited by law from possessing a firearm, and is not a
member of a criminal street gang. The clear intent was to protect law-abiding citizens’ right to carry a handgun concealed for personal protection in
their cars or trucks without needing a Concealed Handgun License (CHL).
BACKGROUND AND PURPOSE
In the 79th session, the Legislature passed a law that was intended to legalize the carrying of handguns in private motor vehicles by persons not licensed by the Texas Department of Public Safety (DPS) to carry concealed handguns. Prior to that, the law had established a “defense to prosecution” against a charge of unlawful carrying of a weapon (UCW) if you were “traveling.”
The 2005 law established a legal “presumption” in Penal Code Section 46.15 that a person was “traveling” if he or she was in a private motor vehicle; was not engaged in criminal activity other than a Class C misdemeanor or other traffic regulation; was not prohibited by law from possessing a firearm; was not a member of a criminal street gang; and was not carrying a handgun in plain view.

Best thing for the OP to do is:
A. Get a Texas CHL.
B. Carry a long-gun (not too handy).
