If the Gross Combined Weight Rating (Weight Rating of Truck + Weight Rating of Trailer) come out to 26,0001 lbs. or higher, then yes - you would need a Class A CDL.
Not necessarily, but specifics matter in regard to this question.
It depends on the state and country regulations. In many places, you would need a CDL (Commercial Driver's License) if the combined weight of the vehicle and trailer exceeds a certain threshold, often 26,000 pounds. However, rules vary, so it's best to check with your local Department of Motor Vehicles for specific requirements.

That depends on the purpose of the vehicle, and the Gross Combination Weight Rating. If it's for commercial use, and the GCWR exceeds 26,000 lbs., then yes, you'll need a CDL. If it's a registered RV, then no - RVs are exempt from CDL requirements.
GVWR of the trailer, GCWR of the combination of the two vehicles, and usage matter. We'd need to know this in order to ensure an accurate answer to this question.
