Best I've done is like 22mpg unloaded at a slower speed on flat ground. Like I said I am switching to 4.10's because I almost never cruise above 70mph and NEVER cruise above 75-80mph and from the experimenting I've done it won't effect my mpg. I just won't be able to get 22mpg at 75mph anymore. But my city mpg will improve.

If I were getting an 8 speed I'd still choose 3.92. At the least 3.55. I wouldn't even consider 3.21, just doesn't make any sense, it's like shooting yourself in the foot.
Thanks for your input. I'll probably end up going with the 3.55's, just because I don't really plan on towing, so the extra few MPG may be better for just my daily drive.
