blctex, I think you misread the statement although I did say commercial license. I have a Class A Motorhome and to operate a Class A Motorhome over 26,000 lbs. in the State of Texas you must have a non-commerrical Class B which is similar testing to a commercial and requires a lot to keep it. In Florida they do not require a Class B.
Here is a good reference to follow: http://changingears.com/rv-sec-state-rv-license.shtml
In Texas anything Above 26,000 lb GVWR or GCWR (while towing > 10,000 lb) requires non-commercial Class A or B
