I have a 2002 Supercrew FX4. I want to put a 4-5 inch lift on it and 33's on my 17inch wheels. I know Wandell said he was getting 13mpg. Anyone else getting anything different. Also i could get a 5-6inch lift almost same price how much more would that affect my mpg's enough to tell difference between 4 and 6. What would 6inch look like with 33's? Thanks for the help!!
