I do wonder about the mountains out west, as we'd like to do a Yellowstone/Glacier trip from the Midwest, so that is on my mind. Even considered getting the 4.10 rear upgrade, with the real negative being that I've heard it will cut gas mileage anywhere from 20 to 50%(!?!), so that really sounds like a bad idea.

A tow truck is a tow truck...mpg is not on the radar. 3.73 vs 4.10...who cares? I've had both and I really loved the zip of the 4.10; it does cut a bit into the mileage but I never even worried about it nor did it seem like much of a reduction. As far as getting down to 25mph, I've never even had a problem getting anywhere close to those kinds of speeds. If you tow, worrying about "mileage" is just something that shouldn't be happening IMO.
