I'm sure this has been asked before, but I'm noticing about 14 MPG around town. I'm guessing it's due to added weight/increased drag from accessories and oversize wheels.
What are some of you out there are experiencing?

I get 16 to 17 city with a 6mt truck. The only difference you have to what I have (weight wise) is a second battery, heavier wheels, and skid plates (my budbuilts will be here soon). The gearing you have makes your cruising around town final ratio pretty much the same as mine with the stick shift. Considering the loss of mpg due to the auto trans, I would say your right in the ball park with all the extra weight.
I purposely went with skinnier tires then most and with lighter weight aluminum wheels inorder to save as much rotating mass and rolling resistance possible. If I was running the same wheels/tires as you I would probably eat 2 mpg.
I was getting 18-20 stock driving in the city in DFW... I installed my Icon suspension, bumper, winch and Nittos in the same weekend and saw an immediate plummet to 14 mpg. I now average 13.5 - 14.5 mpg for the last year (~18k miles). I do see ~16 on the highway though.

According to my Ultra Gage I'm getting an average of 18 MPG (I don't do a lot of HWY driving). I have a 2 1/2 inch lift and 285/70/17 Toyo Open Country A/T II. Before the lift and tires it was close to 20 MPG. I do baby it though. I drive like an old Asian lady who's talking on a cell phone, so I'm sure that helps with my MPG.
