Great pics...
You said no decrease in MPG. How many miles are on your rig. I know of no one here who has put larger tires on their truck and not suffer a decrease in MPG. It maybe as simple as you do not have enough mileage on the H2 for a good baseline w/in the computers. Heck, I know of no one that has gotten a better ride with a lift. What kind of tires are you running? They must be unheard of.
