Hi everyone, MIL has asked around and seems that fill dirt is running 650thb per large truck. I need to fill 2 rai by the end of the year....does that sound about right to you guys or is she getting the special "farang son in law" price?

If the truck is large, and full, say above 6 cubic tonne, then it could be fare, depending on how far the truck has to travel, and if the driver is expected to pay a tax to local enforcement for entering and driving through a municipality. 

Also, it will soon be the annual time for all digging to stop, so I imagine if you're still getting dirt after that time, then you'll be paying a premium. 

For some prospective, my friend lives 20k outside of our small town, and he just payed 250bht per truck from practically next door. 

Where as I have just bought dirt for 550bht a truck, because im 500m from the town. 

I paid 800 baht (thai price) for a six wheel truck load so I would say your getting it at a good price
