The turbo is cool enough to shut down by the time you are at a pump or in the campground!

A lot of the time yes, but too often the temp is still up. When my EGT hits 300 degrees, then I shut down.
My thought as well. Campgrounds generally are enough to cool, but fuel stations rarely are IME.
Based on his sig he doesn't even have a diesel....or a dodge.
Correct! I have a V-10, used to have a Dodge conv van but traded it in on the X. I am a certified diesel tech. and yes by the time you pull up to a fuel pump the truck is safe to shut down, unless your spooling up the turbo waiting in line!
Many people are not aware of how a diesel operates, so I can understand some of the misinformation I read here. this is usually why they post their "reasons" for allowing it to idle. the fact is it is not necessary, unless the gas station is at the top of a mountain on the side of the hwy with no vehicles in line and you pull right up, then yes, you need to let it idle for a few minutes.
Most truck stops I stop at while traveling are right off the interstate and 90% of the time I can drive right up to a pump. I also run a pretty hot tune on a stock turbo so there are times I feel I need to let'er idle while pumping. You would be surprised at the people that tows with hot tunes so your assessment that it don't hurt to shut them down don't apply to all diesel trucks on the road.
