Your instructor was wrong. Travelling was clarified by the Motorist Protection Act, and how you can defend yourself was clarified and redefined by Castle Doctrine. Both were part of the 2007 legislative year.

Its worth studying deeply.
After reading your post, I think this is the exact passage you're looking for:
PC §46.02. UNLAWFUL CARRYING WEAPONS. (a) A person commits
an offense if the person intentionally, knowingly, or recklessly carries
on or about his or her person a handgun, illegal knife, or club if the
person is not:(1) on the person's own premises or premises under the person's
control; or(2) inside of or directly en route to a motor vehicle that is owned
by the person or under the person's control.(a-1) A person commits an offense if the person intentionally, knowingly,
or recklessly carries on or about his or her person a handgun in a
motor vehicle that is owned by the person or under the person's
control at any time in which:
(1) the handgun is in plain view; or
(2) the person is:
(A) engaged in criminal activity, other than a Class C misdemeanor
that is a violation of a law or ordinance regulating traffic;
(B) prohibited by law from possessing a firearm; or
(C) a member of a criminal street gang, as defined by Section
71.01.
(a-2) For purposes of this section, "premises" includes real property
and a recreational vehicle that is being used as living quarters, regardless
of whether that use is temporary or permanent. In this subsection,
"recreational vehicle" means a motor vehicle primarily designed as
temporary living quarters or a vehicle that contains temporary living
quarters and is designed to be towed by a motor vehicle. The term
includes a travel trailer, camping trailer, truck camper, motor home,
and horse trailer with living quarters.
(b) Except as provided by Subsection (c), an offense under this
section is a Class A misdemeanor.
(c) An offense under this section is a felony of the third degree if the
offense is committed on any premises licensed or issued a permit by
this state for the sale of alcoholic beverages.
You could still think of it as travelling, but travelling was removed from the text of the law.
Its still picking nits, I know. But having a good clear understanding of the actual law and justifications of it sure makes staying out of trouble a whole heap easier. When you throw in carrying a firearm, a whole bunch of new possible penalties arises.
