New to this site, am looking for input from anyone who has experience & tips for long term happiness w/ this model. Strictly "road warrior" use, 40K miles/yr. Is my 4th Explorer, but 1st V8 & AWD. Live in the NW so do alot of mountain, rain, snow, & dry road conditions. Any "good" tricks to improve mpg? Currently running @ 17-18mpg. My 4.0 was @ 19mpg so really cant complain. Ideas out there? Thanks
