Correction... sorry, It's an I 280 Isuzu Pickup...
What are the differences between the GM trucks and the Isuzu I 280's? Do the Isuzu's use their own engines/drivelines, or are they the same as GM's?
GM toyed with Isuzu engines for a while as well as Honda. An Isuzu engine is an Isuzu engine, it is not made by anyone else.
