    We are retiring in 2005 and have our equipment (F550 Ford truck and 35'Hitchhiker 5th wheel) My question is about air deflectors for our truck. Is there advantages or disadvantages in putting one on and which one do you use?

    Simply stated, they are gas savers. There are several on the market but the one to buy would be one that is adjustable and look at quality as well as long term reliability and structural reinforcement. The cheaper ones have a problem that they do not have the ability to sustain long term usage because the air passing over them sets up vibrations thus leads to fatique cracking over a period of time.

    They are advertised as gas savers, however I have yet to hear of anyone who actually has seen a significant improvement in gas mileage with one and have heard from many that no significant savings were seen. What they are provably good for is reducing the number of bugs squished on the front of your trailer :)

    Hi nanablue, take the money they want for one and buy a CD at your bank and you'll have many times more money to spend on fuel then you'll ever save having the deflector on the roof of your truck. This is from personal experience you'll see on a good day 2/10's to 3/10's of a mpg better fuel milage, when you get to your destination you have to remove it or you'll see 2 to 3 mpg reducution when running around with no trailer. They work for the truckers because 2 to 3/10's gain when you drive 200000 to 300000 mile per year counts up also if you take note heavy trucks have more then just a deflector they have a complete areo-dymanic kit on the truck. Good luck
