    Mystery F900's that belong to an unknown heavy haul company. I don't know where these trucks are located but I sure would like to know if they still exist! Impressive vehicles with Mack 100-110K plani drive axles on 14.00R24 rubber!

    I found out these trucks are still working to this day in Iran where this photo was taken!
