In Texas if your MH's GVWR is 26,001 lbs or more then you are REQUIRED to obtain a Non-CDL Class B license to drive the MH for private use. The written test consist of a 20 or 25 question, can't remember the total number, and a driving test in the over 26,001 lbs vehicle.
I just took mine a few weeks ago and all of it was easy for me. The written portion is covered in the regular Texas Drivers Handbook in section 15 with 2-3 questions coming from the first part of the manual. A set of sample questions is included in the manual.
Texas has a form that exempts RV's over 26000 when driven for personal use. I had my license renewed last year and all I had to do was fill out the form in front of the examiner with the box checked.
