how much firewood?

[SmollBrain 🏹]

I have the trailer pretty much full to the top, but it just keeps getting bigger and bigger. Is there a certain ammount you need for the mission?

Dont think so, the amount you bring determines the amount of money you get.

If it keeps growing, just add more. You will see that it is not getting bigger when it is full, even though you can add more after that.
