I have had my Ranger for about a month now. And so far it is one tough little truck. The highway mileage is about 22-23 mpg. In town only about 15. The a/c will make my ears go numb. The 4.0 has more than enough power for my needs. This truck is a keeper. It is still too new to judge it completely though.
Ease of use for this truck is perfect. All controls are where they should be. The dash is well laid out and easy to read. The base stereo is great.
