If it does effect ur mpg, approximately how much.
Some guy told me that it didn't because it carried weight rather then rolling weight (not sure what that means or if it's even true).
What is u all's outlook on this?

He was referring to sprung vs. un-sprung weight. Yes, inertia will play a larger roll in conveying sprung weight than un-sprung, but any extra weight will result in some degradation of fuel efficiency. The Wikipedia entries on Spung and unsprung mass are better tools than this post at explaiing this. Good luck.

Jeeps are not exactly an aerodynamic vehicle, so what's one more flat surface?
My MPG are unaffected by the addition of my winch and bumper. However what I did notice was about a 1 MPG gain when I added the front skid plate. Go figure

IMHO - anything that adds weight without decreasing wind resistance has to negatively affect MPG.
You may not see the difference if you are using your jeep computer to measure your gross fuel economy.

I can see a bumper having an affect, but not sure it is the aerodynamics as much as the weight.
One of the posters said her bumper weighed 150 pounds and winch another 70; my bumper and winch combined don't weigh 150 pounds. The variance in weight between bumpers is huge.
