When other TCers see my air dam, they always ask if it does any good. I will let the pictures answer the questions.Pictures were taken after returning from a 1,250 mile trip to the Texas Truck Camper Rally in Kerrville, TX. Speeds were 60-70 mph. Some night driving.Nose and air dam:Portion of air dam (luna moth):Driver side under overhang:Passenger side under overhang:Does it help get better fuel mileage? I can't really say, but I am not trapping as much air on the front of the TC and the noise is reduced also.

That looks interesting. I'm wondering what that must be made, of some sort of flexible material and makes contact with the truck roof?Is there a how-to thread?

I've been interested in adding one to my TC but it is fiberglass with no pre-existing screws to use for attachment. Has anyone installed one on a Bigfoot, Northern Lite, or other fiberglass TC? I've wondered if the 3M or similar tape that some use to attach solar panel brackets on the roof of such campers would work for this. Would there be problems with fatigue failure of the fiberglass with constant flexing of the air dam as the load on it changes due to changing speeds? I'd think an air dam with its surface perpendicular to the air flow by design would have a higher load and a higher load range than a solar panel that is mounted with only a narrow edge perpendicular to the air flow.

Hey Jumbo. Don't mean to take this string off topic, those air dams are great. But, is anyone going to post from the Kerrville rally?

Can you post pictures of the Air Dam mountings and with the TC loaded on the truck?
