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.
yes it is legal to drive your truck in Texas with the tailgate down.
Keep the tires at the correct pressure, tailgate up, drive for mileage as in slow starts, and driving the speed limit. Remove all weight you do not need to carry. Use the A/C on the highway and turn it off in the city. If the truck is tuned up and running as good as possible that is about all you can do. Pick-ups do not get great mileage and if you own one, especially a full sized truck, you live with it.
yes
It is technically illegal to drive with your tailgate down in Tennessee. This is considered to be an unsecured load, even if there is nothing in the bed of the truck. This is only considered a violation.
Depends on the fuel mileage of the truck in question.
its called a tailgate(:
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.
Cars get better gas mileage but have very little storage space. A truck is better for hauling things around, but not great on mileage. I think the ideal situation for a two vehicle household is to own both a car and a truck.
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.
Depends on how you drive it. At 60 MPH with the tailgate down and no A/C, I get about 23 mpg. At 70, I get about 20 mpg. At 55, I get about 24 mpg. Turn on the A/C and the mileage goes down a bit. Open the windows, and the mileage goes down a bit. Drive like a bonehead (speed, jackrabbit), and the mileage goes down more than a bit. Terrain and weather will affect it, as well as tires, tire inflation, maladjusted brakes, etc.
Yes. However, you are responsible for ensuring any cargo or other items you have in the bed are secured.
When you buy, you can drive the truck as much as you want. But, when you lease a truck, you are only allowed to drive up to a certain mileage, and if you go past that, it will really add up in cost.
