Trucks a 24 bought new in June. Changed oil at 970, 3,000, and just before our trip at 6,000. I also have the Range module. SW FL to OH. I really love this truck to travel with. Its very comfortable, cooler/fridge plugged in in the bed was nice to have. Loving the heated seats and steering wheel in the cold. The engine seems to be really comfortable at 85-90mph, closer to 90 if I'm honest. Coming through the hills of TN I bested the 18.5mpg best it said from the factory with an 18.9mpg. Never thought I'd see better than that 18.5 number. If it wasn't broke in before the trip it is now. Since the wife and I decided to add another pooch to the family this January we have committed to spending time on the road rather than in the sky for our annual trips to Northern MN in the spring and the fall. I will be swapping out the Good Years for something with a higher speed rating for the spring trip. My kids and grandkids will be the beneficiaries of my remaining Delta Skymiles to come visit ahh...uhm...gulp...Grandpa. That word.
