I would check to see if you have a sticking caliper, air in the tires ect. Also you need to remember that the fuel they use in the winter has more ethanol in it so typically we get worse mpg in the winter than the summer.

what gearing? It sounds like his gearing might be too tall. In comparison, your 33s might help your gearing and mileage. My truck, 350/350/4.10/30s is geared way too short to get good mileage, especially if I wanna go more than 55ish. It wouldn't surprise me if a modest tire size increase helped my mileage.
