Its the one involving the collection of 3 specific items and placing them in a vehicle. I've watched a Youtube video that shows you exactly how it's done but it's not unlocking for me. I'm sure someone here knows what achievement I'm talking about. I need tips.
Here's the video to show what I'm trying to do:
I've collected all the items but it's just not unlocking. I don't get it.
OK I just got it. I ended up using the "large box" as the container for the items. Despite it being fairly small and hardly being able to hold all of them, I unlocked the achievement instantly after I placed the last item in.
Hopefully this will help out someone in the future. Remember: Use the "large box" if you have it availiable.
