3.31 vs 3.73

I'm debating whether to order a 148 medium roof with the 3.5 eco with the 3.31 or 3.73 limited slip rear end. Do you guys think mpg's would be affected that much with the 3.73?

3.73 made sense with the 4spd transmissions in the older trucks. It's overkill with the ecoboost and 6spd IMO unless you need maximum towing capacity.
