|Our first stop after leaving the campground was a grocery store. On the way to the store the truck started having problems. After sitting at the store it seemed to be ok so we continued on our trip. We really enjoyed the beautiful orange, gold, and red leaves of the trees along the interstate. We were in the highest part of the mountains in the middle of a construction zone right before Asheville when the truck started acting up again. We were able to get off at the Hendersonville exit and found a GMC dealer. It turned out to be a dirty fuel filter. After getting a new one installed we continued on our way to Sevierville, TN.
