Hi guys I just ordered a 13 FX4 SCrew Ecoboost with 5 1/2 foot box. It is not a max tow and it has 3:55 gears. My question is does anybody real mpg average pulling a 22 foot 4 place open trailer. I'm prob never gonna get a enclosed cuz I hate how they pull in the wind and love my Aluma open. I know its not gonna be the greatest I'm just curious. Thanks guys
