Not much to report at all with this truck, other than I found my scary engine rattle - turned out to be a loose alternator belt allowing the fan to slip. Now that it's not, I definitely know I need to get a clutch fan!

Truck has been working hard. I just went on a 160 mile trip to pick up an air compressor, cruising between 60 and 70 most of the way, and was pleasantly surprised to get 12.2 MPG average for the trip. That's better than my 307 1/2 ton!
