OK, survived the road trip from Colorado to Nevada, 1000+ miles, across I-70 and US Hwy 50 - a.k.a. America's Loneliest Highway. No failures!!! Some fantastic scenery not normally observed.
Of notes on the drive: Fuel gauge sticks at times, drops 1/8 of a tank after jumping for 15 minutes (suspect the tank sender). Oil pressure gauge had a few fluctuations part of the second day, but otherwise held at 40-42 psi when at running speed. And a strange whistling noise near the charge air cooler when boost is on when climbing hills. and it fluctuates when the cooling fan kicks in. I'm very glad that I had my drive shafts rebuilt, fuel and oil filters changed, and general maintenance. 20,000 lbs of truck, 300 lbs of tools and parts, 300 lbs of lumber in the bed, 200 lbs of me and luggage, and pulling the 5,500 lb Zombie Truck (flat tow).
Found most of my fuel charges and present these results:
High of 8.6 mph, low of 3.6 mph. Low was climbing from the Utah/Nevada border into Ely, NV - lots of headwinds. But there was lots of hills through the whole drive, including 10,250' outside Vail, CO.
Speeds were held to 45 mph except downhill (50 mph) and uphill (30 at times).
Nothing pre-pressure transducer to compare with though. But still impressed with the mileage.
Of note: The steering seems a little heavier with the higher pressure transducer, and I noticed that later in the day, after driving a while, the CTIS would insist on topping off pressure in the tires while driving, rather than just test and go.
As it is said, your mileage may vary...
