CDL is for COMMERCIAL use of vehicles.

Your State most likely has a 'Class A' license that allows you to drive a large vehicle. PA does:

Non-commercial Driver's Licenses

CLASS A (minimum age 18): Required to operate any combination of vehicles with a gross weight rating of 26,001 pounds or more, where the vehicle(s) being towed is/are in excess of 10,000 pounds. Example: Recreational Vehicle, when the towing vehicle is rated at 11,000 pounds and the vehicle towed is rated at 15,500 pounds (total combination weight of 26,500 pounds).

I drove my 1966 M35a2 (23,500 Gross, can tow 10,000) without a CDL legally.

You want to drive legally, but you sure as heck don't want a CDL (go ahead and try and figure out IFTA and log book crap).

Check you State.. that's the only way to be sure.
