I could live with 13-17, but like I said I think the guy is full of it. So I'll see.

I always wanted a 4x4, my wifes likes them, we could use a CC, and only Ford offers the straight axle. I don't think IFS is good for 4x4's. Although it would suit more then my needs I would just end up trail riding like I have done in 2wd's.

The one thing I have noticed from friends and such is there is really no mpg benefit in a 1/2 vs 3/4 ton 4x4. Thats why I would go 3/4 ton. I would only do a leveling kit, Nitto Dune grapplers, and a few bolt-ons
