I have a real CDL only due to my employment for an RV dealer, however, no special licensing is required for any RV in AZ.
My question is why this special licensing is being called a Non-Commercial Commercial Driver's License (CDL). It's very confusing. The RV license, as it should be called, has nothing to do with a real CDL.
BTW I've seen people drive off in 45' diesel pushers with zero prior Class A experience other than the test drive.
