I have used it a few times back when I was in northern Indiana. I liked the idea of having an alternative. I do not plan on using it much but when I bought the Commander it seem to tie into the go anywhere idea about building an expedition Jeep. You never know what the future might bring and it is just another example of what might someday come in handy. I am one of those guys that really do not pay much attention to gas mileage other than miles to empty. That is why I carry 50 gallons of gas around.
