Ol Smoke Posted May 25, 2013 Share Posted May 25, 2013 I saw show on Mythbusters about this and they came to the conclusion that having the tailgate up gave them more mpg. On that show it showed that a bubble of air was created in the box and the oncoming air was directed up and over the tailgate very smoothly. I always thought that putting that screen mesh back there was a bad idea. I guess I was right. NASCAR did a test on their truck series trucks and found the same thing. Tailgate up was better. Here is a test from Chevy. See what you think. http://www.foxnews.com/leisure/2013/05/20/tailgate-up-or-down-gmc-solves-age-old-pickup-truck-mystery/?intcmp=obnetwork Happy trails.

You mean with the tailgate up you would create LESS drag. Which results in higher mpg. Quote Link to comment Share on other sites More sharing options...
Eggtato Posted May 25, 2013 Share Posted May 25, 2013 Well now I look like an idiot. Maybe I should pay more attention in science. Smoke don't listen to my post listen to ajnl. Quote Link to comment Share on other sites More sharing options...
KevinBacon Posted May 25, 2013 Share Posted May 25, 2013 Someone should test to see if the same truck can attain better MPG with a camper shell, or a tonneua cover (or however the f*** you spell it) Quote Link to comment Share on other sites More sharing options...
Ol Smoke Posted May 26, 2013 Author Share Posted May 26, 2013 I actually recognized this phenomenon when we were driving down a dirt road one day with the tailgate down. (Yes wolfie down) The dirt cloud behind us seemed to be swirling inside the bed of the truck instead of streaming behind us. So I stopped and put the tailgate up and then looked back and it was clean air behind the truck for about 20 feet. So ever since then I have always traveled with the tailgate up and also because the truck looks better with the tailgate up. Wolfie you get a C- for not paying attention and a D- for not correcting your spelling errors. 1 Quote Link to comment Share on other sites More sharing options...
