Dear Mr. Natthapoom,
Could you please explain more detailed? I don't know what there is the length difference between the spec. and the truck assembled in TCMA. How many is the difference? And what kind of parts which you need the materials data? What is the competitor's truck material data?
I'm working in Pathum Thani office almost the whole days from Monday to Friday. I think it's more better to inform me firstly regarding to the detailed matters. And it's not enough just to discuss by email.
If you have any question, please feel free to contact with me.
