Sorry to hear about your neighbor TACWUT. Sending prayers.
As for gas mileage, my 2010 was horrible and I tried everything, including being gentle on the throttle. I honestly have never owned a truck that got worse gas mileage. My 2000, of course it's a 2.7L gets great mileage. When I traded my 2010 in after my accident, I said screw it and got a 5.7L Tundra CrewMax. Damned if this thing doesn't get the same mileage (or better!) and it's a shit-ton bigger and all that friggin' power. It doesn't make much sense to me.
Damn, the 2nd gens need a more efficient V6...WAKE UP Toyota!
