How to get the fuel truck to appear at the designated airport？
I made a CNAF texture myself. But I can't let it be used only at the airport at the beginning of Z.

title=FSDT_FuelTruck_TZA45FM_CNAF_Truck
model=truck
texture=CNAF
couatl.trailer = FSDT_FuelTruck_TZA45FM_Shell_Trailer
couatl.fuelman = FSDT_FuelMan_01_shell
couatl.icaoprefixes = Z

I did this, but it didn't work. Still mixed.

What do you mean with "still mixed" ? Your configuration asked for a Truck with a CNAF livery, but with a Shell Trailer attached to it so, if that what you mean with "mixed", then GSX is doing exactly what you told to do.

So, in your case, you should have done the trailer with your custom texture as well.

Hi,
It still doesn't recognize. I think couatl.icaoprefixes can't be used in fueltruck. I called Fueltruck at ZBAA, but it was bp or something else, not CNAF.
