Last December I upgraded from a pristine 12 year old Tundra to a low mileage F250 V10 Lariat CC. We needed a more capable tow vehicle and we needed more passenger room. In our case, the tow vehicle isn't used for commuting and sometimes sits for weeks at a time. Our "new' toy hauler will never exceed 8000 lbs and will only be used for hauling bikes a few times a year. A gas engine just made more sense. I've towed both our old toy hauler and our new larger one with the F250 and I'm real pleased with the difference. The thought "Gee, I wish I had more power" hasn't crossed my mind yet.
