Need advice for a first time MH renter in the Atlanta area

I know that Lightning RV in Lawrenceville rents Cs and As. Whether or not they are a 'good company' I cannot say. They were very nice when I dealt with them a few years back when they actually sold campers. They are right on 316 just about 1/4 mile south of Ga 20
A good shake down might be up around Lake Lanier or Lake Hartwell. If you find you can handle it ok, then maybe Dillard Ga at River Vista
