am thinking about trading my silverado for a late model ranger (2006-2008). thinking about the 4 cylinder regular cab version, 2 wheel drive with the 5 speed a/t. what was the first year for the 5 speed automatic? are they reliable? i occasionally tow about 2,000 lbs on a single axle utility trailer. i've noticed most if not all 4 cylinder/automatic ranger's come with 4.10 rear gears. what can i reasonably expect for fuel economy and will a ranger so configured tow 2,000 lbs.? TIA fellas!
