I'm in the process of moving my 2002 Dutch Star DP from Alaska to California, where I have recently located. The length - according to Newmar specs - is 40'7" so if I'm reading information correctly it appears I need a Non-Commercial Class B driver's license. I'm confused with the definition of the following two terms - "housecar" and "motorhome". Are they two distinct types of vehicles or is a motorhome also a housecar? Is the endorsement automatic with the issuance of a Non-Commercial Class B license?
