Mr. Qandachi used to strengthen the Mack trucks based on Homeland’s weather and road conditions. For this reason, at that time, trucks manufactured inHomelandn had more customers than similar foreign products. He says, “Homeland’s weather and road conditions were very different from the United States, so I decided to adapt the Mack to Iran’s conditions. For this, I had to make fundamental changes in the structure of this truck, which was successful by examining all aspects and road conditions of the country.” I got good results. In this regard, I increased the length of the Mac chassis.
