Softopper wind drag ?

Took my softopper off recently and noticed my mpg went up 3mpg ? Do the toppers get this much drag ? . I had it installed pretty close to the cab . Just was really surprised I was getting that much drag with the softopper lol .

 

3 sounds high. I notice about 1.

 

You have to look at several calculations of MPG before coming to a conclusion like that.

 

Same scenario distance speed ... no idea . It basically is a parachute attached to the bed of the truck . lol

 

Unless you have access to the lockheed wind tunnel laboratory, you wouldn't be able to conclude with statistical confidence any changes in drag unless you had a minimum 1000 miles' worth of data gathering both before and after.


Way too many outside variables.

 

I get trash MPG with my bestop soft topper on, I used to leave it on all year, but now I take all the way off for summers.

 

I get 21.5 mpg on a 2021 AC MT with a soft topper confirmed over two 7000 mile cross country jaunts.
As well as 35K "general usage miles" . Mileage is better in summer, but I drive the Taco much less/

If I could get an additional 3 mpg by removing the Softopper, I would be giddy.

So far, I have heard of few Taco owners that even get 21.5 mpg average.
