Its a lot more complicated than having only a truck that can gross over 26000--a lighter truck and a trailer over 10000 in a commercial use will require the CDL in TX. As I stated, my gross is over 27000, but the truck is at 14500--if for some reason I was checked for weight, I could be cited.
I actually should have a 'non-air brake' CDL which actually is easy to obtain--but having a CDL will at some point complicate my insurance, when the 450 is taken into account. And--can't get a speeding ticket dismissed with a defensive driving course if you have a CDL.
All-in-all, RVers are almost never stopped/cited unless doing something else to get attention, like double towing....

Terry, question: on the registration on your 450, does it have ANY reference to weight/carrying capacity/weight rating? Mine says 11000--tried to tell the county clerk it was higher, but her book overrode my opinion...She did say I could register if for any weight I wanted, but the cost jumped quickly, so I agreed with her book.
