I installed the air tabs on the driver’s side and the roof. For the trailer’s corrugated side I used a piece of white drip edge with 1/4″ thick pieces of wood to fill the hollows and caulked the leading edge. I couldn’t be happier with the results!!! Except for when a truck overtakes me while on a left-hand curve I no longer feel any effects of the trucks, wonderful, wonderful, wonderful! I don’t even care about any gas mileage savings and would have paid well over $1,000 for your product had I known how well it works for passing trucks. I no longer fear their approach in my mirrors. You’ve got a real winner and I am surprised by how few I see on other trucks and campers. Thank you, thank you, thank you.
