this is a custom lego vehicle i came up with after seeing a bunch of lets plays of fall out, i based it on a sand crawler from star wars and started looking up a bunch of different lego models of machines and reactors and made some from scratch, its equipped with several rooms for living in, a fully stocked machine shop, fission reactor, moisture condenser and water purification system, a large green house on the back, an internal respawn station for any one entered into the system. and a nanite based maintenance system that uses raw materials such as scrap metal to maintain the crawler, and the micro fig shown is to show the scale of the thing, and i'm really proud of it. though it is open to updating and changes

length: 2980 feet
height: 500 feet

weight: 3065 tons

lego belongs to lego.
the model shown and its design belong to me.
