Yes, all mega cabs are on a 3/4 ton chassis. I can't remember the exact difference in the towing and payload between the 1500 mega cab and the 2500 mega cab but it is not much. I'm not sure about the the fuel mileage on a 1500 mega cab though. I know the 2500 mega cab with 4:10 gears is way less then he says the 1500 gets.
