I am considering buying a 08 or 09 4 Runner and would like some feedback from owners regarding what sort of mileage to expect. I recently rented an 08 V6 SR5 4wd 4 runner in Jackson Hole Wy and got close to 27 mpg overall for a weeks driving to and thru Yellowstone, Tetons and in Jackson town --600 miles for the week. This seems too good to be true, but based on miles and gas replaced, the onboard computer seems accurate . I don't know if the altitude has anything to do with it. I live in AL and at about 600' rather than 6000'. Can I hope for anything close? If I chose a V8 (i have a 4500lb boat/trailer to tow) what would be reasonable? Thanks for all input.
