axles - 800 w/tires (200 per end w/brakes, 100 per tire)

there's well over 3000 lb worth of stuff listed and I missed more like seats, interior, windshield, tailgate,...
I think mine's prolly a heavyweight for a glass tub - since I've got a bunch of steel added on, but you're around 2400# before you get to the body.
