    I never realized what a difference the wind makes in a motorhome.
    :Rofl1:

    Drove for 2 hours to a site in a 30 mph headwind all the way and used half a tank of fuel.
    Drove back the next day with a tail wind of 30 mph and used less than half of the day before :thumb:
    What with the cost of this liquid gold nowadays, will it be be better for us to now pre plan with the weather forecast (as in aviation ) as to what direction we want to go to save fuel? :Eeek:

    The fuel gauge may not be 100% linear but the head wind will make a big difference especially with the big frontal area of a van. Just try cycling into a wind and then with a tail wind to see the difference.

    Tuck yourself in behind a big lorry, makes a big difference, you will know when you are at the right distance as you lift your foot off the throttle.:thumb:

    That is an idea, fold it down into wind---pull it up with a tailwind--now there is a invention waiting to happen.
    Car manufactures spend millions shaving .005 mpg off of a new model-- i could knock someting up that came from a ebay :thumb:
    I don`t know how i would get on trying to tack accross the wind though :Rofl1:

    If you don't want to watch the full video here are the results.

    @ 55mph First column is the distance 1st is dry run no truck to get baseline.
    Second column is the mpg
    Third column is the % improvement over the baseline...

    Normal: 32mpg
    100ft: 35.5mpg 11%
    50ft: 38.5mpg 20%
    20ft: 40.5mpg 27%
    10ft: 44.5mpg 39%
    2ft: fuel economy dropped back a bit from the 10ft test
