I'm sure you can. You can look at their different options online. It will be more expensive than a regular car though.
I'm sure you could, but you will probably need to advance book or rent what's available. They did have a couple of big trucks there when I came in (4wd?). I called the day before for a ride/pick up to rent an economy for the day, from Cumming to Blairsville.
