No, it's because of winter blend fuels. Denser (colder) air actually increases engine efficiency.
But people also sometimes forget that the colder air causes the ECU to keep the fuel mixture richer during warm up, which takes longer in colder climes/months. All the "little things" can add up to lower mpgs, like a bit of spinning tire syndrome on ice/snow/etc.
Sounds like you're about normal OP...

Mine dropped from 18 MPGs to 15.9 MPGs since winter blend fuel and cold weather arrived.

I agree. If you cared about the gas mileage don't buy a truck. It will always never be what you want it to be. Until the day you come to realize that 15 mpg with a 7000 lb truck 400 hp V8 or a big turbo V6 isn't really that bad then you'll always be disappointed. Don't ever but a truck for mpg but it because you wanna tear up some mud or pull something heavy than that Chevy next to you.
