Its possible. I have an SC, 33's BL & SL + Armor and have gotten 20+ mpg. The secret is to go with rigs with 35s who can't get above 45-55 mph. I guess the SC helps keeping the X going at low rpms in 5th.Desert Rat wrote:Add 33's, lift, and armor, and forget about it.
The only way my Xterra will get that mileage is on the back of a flatbed.
