I went to Atlanta and yes, they had a lot of RVs there but not so many vendors.. Since you want an RV, might be a good show for you.
FMCA rallies (Google Family motor Coach Assn) often have dealers as well as vendors and more.. Of course I'm not sure if the public is welcome to everything but for sure if there is a rally near you the dealers will chat with you.
Where in GA are you located.. I'm in Townsend (near Darian) 3 miles From I-95 exit 49.
Home is where I park it!
