Just out of curiousity isn't that hard on the engine just idling it there for 9 hours at a pop? What does that do to your MPG?

yep, i'm sure it's not good on it, when I started my DIC was at 31.2... at the end of the day is was at 17.3. By the time I got to my folks house for the night (30 miles highway) it was back up to 25.3

I did a lot of sitting/idleing last summer in my Silverado extended cab and it's still running strong. I run Royal Purple oil in the engines so I would think that probably helps some. I was honestly surprised that the temp didn't go overboard though. I was working with another investigator and he was in a Dodge Stratus and he did not have any temp problems either.

Normally when the weather is not so warm I just park and roll down or crack a window or two. But when the temps are up it's just unbearable to sit there for long periods without the engine and a/c running.
