The door skins are 3mm thick and weigh 60 pounds.

That thin!??

Oh well, if it will stop some feral's bullet, good enough for me.

That’s just the door skin. Then there is the internal structure of the door which is typically 1.5 times the weight of the skin.

And that is just the metal. not the window or the electric junk.
