the 3.0 hasn't made sense in years, the 2.3 has almost as much power as the 3.0, but the 3.0 gets just about the same gas mileage as the 4.0, with out the power. but you are correct, it was a popular choice when purchasing a new ranger, people often thought that the 3.0 would get alot better mileage than the 4.0 and that they just "didn't need the power of a 4.0". i've seen 2.3 wiht the proper gears out tow and out haul a 3.0. not a terrible motor, just outdated....by 20 years.....
