Can someone tell me what the MPG drops down to If i were to go with a 6" lift with 35's, as opposed to 33's and just a level kit?? Im wondering if its worth the extra $$

 

Your MPG will decrease if you put on a level kit a 33's and it will decrease more if you add 6" and 35's. So, to answer your question, no, nobody can tell you what your MPG's will drop down to, only that they will drop. Just put some bigger tires on it, don't worry about MPG's, it's a truck!
