I've been out west (Yellowstone, Utah, Arizona) 3 times and way into Mexico 6 times - crossing the Sierra Madre west of Durango towing a 7,000 lb travel trailer. Steep hills slowed it down but those grades also sloowed OTR trucks down too. I would try to keep the speed up 75-80mph most of the time - the faster entry speed helped get up steep grades a little better. MPG was never better than 11 or 12. I bought this truck new in 1993 and still have it 277K miles later. No turbo, 4.11 axle, E4OD transmission (rebuilt at 220K miles)
