I have gone to the current Transportation code for the state of Texas, so as to provide the most current information.
I have removed my other post so as not to clutter the thread.
I used strikethroughs to eliminate non applicable information and for ease of reading.
I hope you find this useful.

CHAPTER 521. DRIVER'S LICENSES <strike>AND CERTIFICATES</strike>

SUBCHAPTER B. GENERAL LICENSE REQUIREMENTS
Sec. 521.025. LICENSE TO BE CARRIED AND EXHIBITED ON DEMAND; CRIMINAL PENALTY. (a) A person required to hold a license under Section 521.021 shall:
(1) have in the person's possession while operating a motor vehicle the class of driver's license appropriate for the type of vehicle operated; and
(2) display the license on the demand of a magistrate, court officer, or peace officer.
The above section merely states that you must present the correct DL for the vehicle you are operating, if you are stopped.
Sec. 521.030. RECIPROCAL LICENSE. (a) A nonresident who is 18 years of age or older and who has in the person's possession a license issued to the person by the person's state or country of residence that is similar to a Class A or Class B driver's license issued under this chapter is not required to hold a Class A or Class B driver's license issued under this chapter if that state or country of residence recognizes such a license issued by this state and exempts the holder from securing a license issued by the state or foreign country.
This is the reciprocating provision, If ones out of state license is similar then it will be accepted as an A,B,C.

A typical 2015 F350 DRW has a GVWR of 14,000
A typical 2015 F350 SRW 4X4 has a GVWR of 10,000
A typical 2015 F250 SRW 4X4 has a GVWR of 9,900
A typical Heartland 5[SUP]th[/SUP] wheel has a GVWR or 15,500
Example #1
F350 DRW GVWR 14,000 lbs
Heartland 5[SUP]th[/SUP] Wheel 15,500 lbs
Gross Combined Vehicle Weight Rating 29,500 lbs
Example:
Above is a combination of vehicles where the GCVWR exceeds 26,001 lbs, The GVWR of at least one vehicle in this combination exceeds 10,000 lbs(in this case both vehicles exceed 10,000 GVWR). This is representative of a typical DRW towing a typical Heartland 5[SUP]th[/SUP] wheel.
Since it is described in Sec. 521.081, A “Class A” Texas DL is required.
Example #2
F350 SRW 4X4 GVWR 10,000 lbs
(F250 SRW 4X4 9900 GVWR)
Heartland 5[SUP]th[/SUP] Wheel 15,500 lbs
Gross Combined Vehicle Weight Rating 25,500 lbs
This example can be operated with a Class C because the combination GCVWR is not 26,001 or greater. The F250 also falls into this category.
The Texas Class B license has no provision for our rigs unless our truck has a GVWR of 26001 lbs or more, and our rig is 10,000 lb GVWR or less.
