After you talk to MK and he leaves, If you go back to the Lopton radio tower and up to the snowman by the buried K-truck, {The one from the end credits} The truck will have disappeared,

I don't know if it can be found else where but seeing as that snowman is the one that gives you the Player bobblehead I feel like it's implied that was Seb's K-truck and MK found Seb up there,

why is the disk in the pawnshop lore wise have I missed something?

if you do the shutdown ending before reboot you get locked out of reboot ending unless you delete your save and start over...

thought maybe deleting the save file was the way to "restore" the world. looks like that was wrong...

I spent hours trying to find this myself, from double and triple checking radio towers, to looking for obscure buildings. And here it was just on an episode of Pawn Stars. I guess it's true, "you never know WHAT is gonna come through that door"

Thank You
