Thanks for the information. Yes, I'm still working on it. Little by little I can address these issues as I learn them.
No it's not, but I found another trigger on field 58 by a coincident. It seems that there has been some kind of produktion or warehouse there.
I have made a production area there and a big parking lot and when I parked one of my trucks there the first time I activated a trigger to reload the Tippertrailer, so something has been there before.
