"Last night I called Morgan County Diesel Repair for a road service and they came out to help in no time and after going back and forth to get more tools between their shop and the truck stop where I broke down to try and get me started so that they can bring the truck to their shop and that failed and the computer was also reading mixed massages so the boss recommended that I should be towed to international dealer to save me money and time and refused to charge me anything and also went out his way to call a good towing company that ended up helping even more. I just want to say thank you so much for your kindness and god bless you more"
