First regen and first shackle plate replacement

[mgdg]

Well on the way up to West Branch Mich. I was getting 14.5 mpg on the message computer then all of a sudden it started dropping slowly to 12.8 mpg. Correct me if I`m wrong but it seems that I had my first regeneration. Then after a while it started to creep back up and by the time we reached our destination we were back up to 13.7mpg. I didn`t do a correct reading by dividing gallons into miles. When I got home I checked the shackle plates and noticed a bit of wear when I took off the bolts and plates. It was just on the door side of the 5ver. The other side I took off the bolts and plates and they were still good as new. I bought a set at the local rv dealer awhile ago and replaced them yesterday.
