If you do a search on MPG you will find several threads on this. As for compareing others rigs, different places, type of fuel(addities do take away, personal epxerence with some native fuel station that do not add any oxygentaion products, I will get almost 2mpg better than oxygenated) tires(size and types), weight of vechicle will all be different. The taller you go, the more agressive tire you have, the more weight you lug around, the less MPG you will have. So starting with your present MPG, andding the lift and tires you will more than likely lose 2 or more miles a gallon, add a roof rack, subtract another MPG. the 93-94 were less efficent than the 95-97, and IMHO the 97 model year happens to be the best at Fuel ecomany. Some stock ones here in the denver area achived over 18MPG be bopping around here. later robbie
