@Johnny Rebel what's your MPG while off roading (Moab like terrain) with your 37" KM3s?
Haven't been in the mountains since late last summer, so I can't remember what it was on the trails. I don't remember it being terrible, like single digits, though.

When I drive it to work, I usually get between 15-16 mpg on the freeways at 75-80 mph. When I drive it on the highways at 60-65mph, I usually get 17-18 mpg.

For reference, mine is a 2Dr BB non-Sasquatch, 2.3L auto, open 3.73 diffs with Ford Pro-Cal tune running 28 psi in the KM3's. I always drive in Sport mode. If I run this setup in Normal or Eco mode, the mileage is worse in all conditions.
