Apocalypse Mecha Reborn: My Mining Truck FortressEpisode 6

When the apocalypse descends, all vehicles will transform into humanoid mechas depending on quality and function. In my previous life, I died to a monster due to my mecha being too weak. Now that I've gotten reborn to the week before the apocalypse starts, I keep taking out loans like mad despite the risks. Then, I spend all of my money on a mining dump truck, which I've altered heavily while gathering resources. After all, this truck will be my trump card in the apocalypse.
