The first 5 miles were on a fairly flat interstate. At 65 mph I got 23.1 mpg. Then I hit a 2 lane highway and set the cruise at 58. There are 4 hills during the 25 miles drive that it always shudders. The first one is pretty steep. I heard the flapping noise twice on that hill but did not feel the usual jerking. The rest of the ride was smooth. When I turned off the highway, my impg was at 22.3. Yesterday, I had filled up before I left the town where I work and I got 18.2 on the commute home. So, a huge jump in mpg on the same trip - same gas. Then when I drove up our gravel township road, I go up 500 feet in elevation. No cruise but try to maintain a steady 30 mph. There is one steep section where it always shudders like crazy. Nothing this time. When I got home the impg was 21.9. That is the truck I remember from the last summer. I will keep you posted if anything changes. Interested in seeing if this is a fix for you other guys.
