This morning, I got home from my Colorado trip. Of course, that was after everyone else decided to load up and leave at about 8:00 last night while it was raining. Other than stopping for a couple of much needed naps, I pretty well drove all night.
Edit to add more info. Other than my truck, there was two Dodge/Cummins, two Chevy/Duramaxs, and a brand new Chevy half ton with a gas engine (I think he said it was a 5.3, but I'm not sure). The two Cummins, one Duramax, and the gas Chevy all overheated. In fact, the Duramax showed up with out the hood on it, apparently to increase air flow somehow. Funny thing. The ancient, outdated 7.3 IDI got all the way up to 205* engine temp. Kind of tells me something about these newer engines.
