Well... I made it to Wyo today. Left Seattle at 1:00pm Sunday and arrived in Nampa at about 9:30. 109 degrees in Prosser when we stopped for gas. Truck ran great. My ave speed was much higher than I planned! Needless to say gas mileage was only about 15 -16. Today I went 400 miles from Nampa to Evanton in 5 1/2 hours. Truck cruises at 80 so long as no hill. Engine temp got to about 195 at the highest but normally hung around 180 -185. Spiked twice to over 200 on the steepest hills on Sunday between Yakima and Ellensburg and that hill just east of Pendleton. Was able to hang on every hill at 60 in 4th and got a bit warm at the top. Didn't use any oil or water. Had the wind at my back sometimes. I hope the way back next week goes so well. I'll update then! BTW thanks for the links and thoughts!
