No. A CDL is only required in North Dakota when operating (1) vehicles over 26,001 pounds, (2) vehicles that require placards, (3) vehicles designed to carry 16 or more occupants including the driver, or (4) vehicle combinations that have a combined gross weight (or gross weight rating) over 26,001 provided that the gross weight (or weight rating) of the vehicle being towed is in excess of 10,001 lbs.
In this case the combination is over 26,001 but the vehicle being towed does not exceed 10,001 lbs. Likewise, a 9,000lb GVW vehicle pulling a 13,000lb GVW trailer would not require a CDL since the combination weight of the two vehicles does not exceed 26,001lbs.
