In short, no. Let this be a place to discuss this for future visitors to the site.

BTW, WITH the tailgate installed and up the water tunnel looked like this: https://web.archive.org/web/200304142...ffner/base.jpg In other words, removing the tailgate hurt aerodynamic drag. |
i'll bet you added that post
i'll bet you added that post because of all the search engine queries leading people to gassavers.org.
(i get lots of the same inquiries leading to mine...) |
If I may venture a guess, I
If I may venture a guess, I think it's because it was addressed in another thread and he just wanted an end all to say, shut up, look at these results.

I heard if you drive with the tailgate down (not off) there is a slight benifit.

some contracters I've known
some contracters I've known who drive the bigger 8ft bed trucks say removal of the tailgate gets them a couple mpgs and having the tailgate up hurts mpgs.
the pictures u put up "look" like a truck with a 6ft bed. Can't say for sure from just a picture... |
have u guys seen
have u guys seen mythbusters? there ex-special FX pepole and test out myths to see if there true or not. on the discorvry channel.

Well, to be fair, that
Well, to be fair, that pickup looks to be of a significantly different design then the previous one.

there are significant differences in pickup design: bed length is a big one; bed wall height; difference of bed height/bed wall height to cabin height; cabin shape. coming up with a conclusion that applies equally to all pickups seems a bit simplistic. it would be like me insisting, "WAI doesn't work." (which i wouldn't insist) when clearly there are a lot of insight owners who would strongly disagree. it comes down to design differences. arguing about tailgate up/down might be like arguing about which tastes sweeter: a gallon of lemonade with 2 tbsp of sugar in it, or 4 tbsp. instead, all these folks should be either adding a tonneau, or dumping a whole cup of sugar in their lemonade by constructing a properly aerodynamic bed cover: https://maxmpg.org/sitebuilder/images...38-441x315.jpg |
Tailgate up, no question about it
The swirling air mass behind the cab of the truck is going to be there no matter what length bed you have. It is designed into truck shapes, and it's there for a specific reason: To decrease aerodynamic drag created by the tailgate. The deflection effect of that vortex sends the downward wind forces up and over the tailgate of the longest bed truck with which that particular cab was designed to work. That is to say that if you have an 8' truck bed, the cab is designed specifically to create a vortex of sufficient size and flow to redirect the airflow over the top of the tailgate that's 8' away from the cab of the truck.
For what it's worth, the Mythbusters crew talked with the manufacturer of the truck they tested, and they confirmed the recommendation to drive with the tailgate up. Why would the manufacturer tell you to do something that is going to decrease your gas mileage? |

In conclusion, each person is going to have to test, test, test to find out what's best for them. and bed covers, especially the tappered ones would be great ( i can't use one, bummer) but not many people are going to spend the time, energy, money to get stares from other people. I would, but can't right now (job consideration) More opinions and testing needed. lets proceed. |
