Do you see a savings in fuel?
They say it's not true, that it doesn't work to leave your windows rolled down in your car on a hot summers day when you're driving to save on fuel instead of using your AC. And I have heard the same for putting your tail gate down on a pickup truck.
Is it true if you keep your speed constant and drive 55 instead of 65 in your coach. It saves fuel and will save you money?
