The truck is a 1999 Dodge Dakota club cab 4X4 with a V6 gas engine and automatic transmission.

The engine is a 2000 Isuzu 4HF1 normally aspirated 4L out of a NKR 3 ton truck. The NKR was never imported into North America except for a few "demonstration" vehicles, it is a smaller version of the popular Isuzu NPR which uses basically the same engine only with a turbo.
