I'm in Calif, not Atlanta.
Here's what an 18,000 lb vehicle looks like. My tractor, Daisy, weighs that much when fully loaded with fuel and wheel weights. She's hitching a ride on Lester (trailer) and Hester (truck).
If you're going to haul that much weight the fancy-shmancy way (i.e. "legally"), then you need to use a lowboy with a semi-truck and air brakes, transport chains, ratchets rated for 10,000 lbs, etc etc blah dee blah....
