No, leave your tailgate up. Myth-busters once tested it and the segment can be seen at the related link below. When leaving a tailgate up, a pocket of air is actually created in the back of your pick-up. When new air rushes over this pocket, the new air skims right over the top, lowering air resistance.
If you leave the tail-gate down, the new air will get stuck in the pocket, creating MORE wind resistance.
What else can I help you with?
Does riding went the tailgate down save gas?
no riding with the tailagte down does not save gas. when driving, there is a circular swirl of air made when the tailgate is up and this makes the wind coming off the front of the truck bypass the bed and continue over the back. dropping the tailgate stops this affect and droppes the gas mileage.
Does driving with the tailgate down give better gas mileage?
No, it has been shown that driving with the tailgate down creates a sort of wind drag that actually decreases gas mileage. The article I read did not address driving with the tailgate off, however.

Do you get better gas mileage if you drive your truck with the tailgate down?
Not only is gas mileage not improved by driving with the tailgate down or removed, it gets worse. Counter-intuitively, driving with the tailgate down increases the aerodynamic profile and wind resistance, degrading fuel economy. (Mythbusters recently debunked the myth. See link.) See the Related Link for "Mythbusters Episode #43" at the bottom left.

Is it legal to drive in CA with your truck's tailgate down?
Hi Folks, This question is very "Specific"... Doesn't appear to me that this question has anything to do with a person with a load in their vehicle or how to mark it, how many feet the load extends past the tailgate, etc... The "Real" and "Accurate Answer" to this question is a definite "YES".. In California you are allowed to drive your Pick-Up Truck with the Tail-Gate Down... Anything else that you do with your Vehicle, Trucks or otherwise of course "Common Sense" applies here... Thanks and Have A Good Day Folks... No. If you have supplies in the back of your truck that extend a few feet past your taillights, you will need to flag the end of the supplies. If you are just trying to save on fuel by driving with your tailgate down, you may want to look up the TV show Mythbusters. They tested 2 of the same trucks, driving down the same road at the same speed, with the same weight driver... and the truck with the tailgate up got better gas mileage. Air travels over the cab and across the bed without going into the bed. Lowering the tailgate created a vortex in the bed of the truck, which caused more turbulence.
How does the 2012 ram mds save gas?
