The prominent sellers of minitrucks in Thailand are DFSK, Changan
, Suzuki and Tata, but they don't sell vans like the above. DFSK used to sell the V27 at one time though, so there could be used ones available.
The contact for DFSK Thailand can be found here

Alternatively your choice is limited to only the large, Hiace-sized vans or any used Suzuki APV, I believe.
