which vehicles used the 4.3L V6 with the 5-speed manual tranny? I know late 90's through early 2000s 1500 trucks did for sure, but what other combinations? Was there ever a Suburban in that configuration? What kind of MPG can one expect with the 4.3L engine? low 20's perhaps highway-only and highway gears?
