Would a Bestop hurt MPG's?

Not sure if its in the right section but pretty straightforward. Would a bestop get signifigantly worse mileage than a regular camper shell?

 

nevermind im an idiot. Of course it would kill my mpg

Haha.
Shouldn't be too bad.

 

Shit. It all makes sense now

 

maybe by luck but my bestop makes no difference in mpg on or off, windows or no windows.

 

Don't get me wrong the bestop is very attractive because of price and how simple it is. I happen to be paranoid about my mpg's cuz im a brokeass.

 

The only advantage besides price is it's easy to remove when not needed.
Less secure & more wind resistance than a hard top would be the disadvantages.
