So weird to me that Isuzu changed to a different compressor for the last model year of the VX. I just don't understand how that makes sense from a manufacturing/cost efficiency perspective. Marlin you're sure that Isuzu didn't use the same compressor in any of their other vehicles at the time? That's about the only reason I could see for changing it up; if Isuzu was going to get a volume discount for installing it across their product lines.
