I tried to look up the applicable Tx statutes concerning licensing boat trailers in Tx. Here is what is in the Tx Dept. of Motor Vehicles web site. Apparently no one knows just what the statutes in Tx are.
I found nothing that stated that trailers owned by Texans had to be registered in Tx.
"Trailers
Texas laws regarding trailers are as varied as the state population, and depend on the type of trailer, its weight, and its intended use. To determine the exact laws for your particular trailer and situation, it would be wise to contact the Texas Department of Motor Vehicles to advise you.
Generally, all camp trailers are titled and registered. Also, any trailer that will be used or pulled on public roads will need to be titled and registered.
However, trailers weighing less than 4,001 pounds are considered "non-titled" trailers, so you may need to register it, but not title it.
Farm trailers also receive special consideration, so check with the county to determine whether your trailer qualifies as a farm trailer.
All registration and titling duties can be completed at your county tax office.
Trailer Registration Fee
All trailers and travel trailers weighing less than 6,000 pounds―$45All camp trailers weighing between 6,001 and 10,000 pounds―$54In addition, you'll also be charged a county fee, which, depending on your county, will range from $5 to $11.50."
