Tennessee is the same. No special license or endorsement (air, weight, or length) and tags cost the same for my cars and the motorhome. No inspection in 95% of the state that I know of, I believe a couple counties in middle and maybe west TN does vehicle inspections but that's all.
To answer original poster question, call an RV dealership about delivery drivers in your area, or do a Google search. Would cost a little bit they could drive you to the testing center.
There is driving schools, I remember Lazy Days in Florida has one, but I'd say there's one close to you if you do a Google search
