Right now I'm about 60% towing & 40% non towing. While I do appreciate the 23-25MPG unhooked with the RAV4, I realize I will most likely not get that king of unhooked mileage with a truck (well, maybe if it was a diesel, but I'm not going there). As to the 15MPG towing, somehow that seems to be a magic number. For almost everyone towing, no matter what the tow vehicle, 15MPG keeps popping up. I'd hope to get that with a Tacoma or Frontier, but I'm also looking at the Colorado.
