First and foremost in Texas you will need, as a minimum, a Non-CDL Class B driver's license to be legal to drive. This requires both a written test and driving test in your coach. I suggest Seguin or Uvalde as DPS testing sites as the towns are smaller and traffic is not so bad. Several of us in this area have solicited the services of a licensed school bus driver for training. I suggest that you do a search of Texas "Non CDL Class B License" in the Class A forum and you should find several threads on the subject. I know there are several fairly recent threads specific to the San Antonio area that should be helpful. In addition, there are some excellent "lazy Days" driver videos on You tube that helped me a lot.
Other than that, you may be able to find a Class A owner locally to help you out. I don't know of any professional services in the area.
Good Luck and congratulations on your new coach.
