Compared to the player model and the car it is laughably small, i kind of expected it to be much bigger because it looks like a volvo mining truck or something similar, and it has heavy in the name.

I guess people could have different opinions on this, so I should make it so the inventory size is configurable when i have time to do so.

I the meantime, you can unzip the mod to your factorio folder, and open prototypes/entity/dumper-truck.lua in you favorite text editor.

Scroll down to the end of the file, at line 287 you'll find the inventory_size property which you can change from 150 to whatever number you wish.

Enjoy !

Nvm, I uploaded a new version. Inventory size is now a setting.

I meant the size of the sprite
