I know the 6.2 is not the most desireable motor on earth, but if it would make the truck economical and useful to drive, plus fit the "clean" image I think it would be worth it.
I have only driven the truck a little bit, but it currently seems to get about 6 mpg
So the nearest trail is actually 74 miles from my house. So that is 25 gallons just to get to the trail and back. At $2 a gallon it is $50 just to get to and from the CLOSEST trail! Obviously if we go back to $4 a gallon something needs to change on the truck to make us efficient at all to use. I would really like to get it to some of the trails around here that are 200+ miles away.
