How much should I expect to lose?
Before I ask, I realize that driving habits will play a big role, but I know the tire/level will as well... So...
Roughly, how many MPGs should I expect to lose when going from a highway tire to an all terrain tire, and leveling my truck (I assume 2" in the front...)?
I currently have Continental CrossContact LX20 with ecoboost technology on 20" rims.
As of now, the computer says 18.7mpg. I drive about 75% highway.
I don't gun it or speed or anything crazy.

I would say a good rule of thumb for a level and tire upgrade/change would be 2-3MPG loss.

It is rolling resistance. I've seen a pretty consistent 2 mpg difference between All Terrain tires and a true Mud Tire. Same vehicles, same E rating on the tires, same tire size, no lift, every thing stock. Just MT's vs AT's.
Start lifting, adding weight and hurting aerodynamics with accessories and you'll lose another 1-2 mpg.

Tire weight, rolling resistance, wind resistance due to the nose of the truck riding higher all contribute to economy loss. I'm currently getting 11mpg city on a 4" lift, LT 35x12.50x18 BFG K02 AT's and a custom 93 race tune with spirited driving.
Honestly if you really worry about fuel economy, should you have purchased a 7000lb truck?

I did just a level on my truck 1st. Ran it that way for a year. Didn't loose any MPG's. Added 285/55/20's up from 275/55/20 and they were 21 lb heavier all terrain tires. Lost about 2 MPG. Got a tune from MPT and gained 1 MPG back. SO overall, I'm down about a single MPG.
