Why Do You Idle?

Sure, starters are... But turbos are well worth a 5 min idle time at least.

 

Because I can, and to rub it in on the garbage outfits with idle restrictions.

Some people have different tolerances to temperature and humidity. If its 70 or more outside it may comfortable outside, but if you shut off your truck you are dealing with your own free furnace for a couple hours due to engine heat.

Also high sun and 65 to 70 degrees with little or no wind can get the inside of the sleeper cookin, especially if there is a lot of vinyl upholstery.

Me personally I need the temp inside the truck to be 72 or lower with low humidity to sleep comfortably. Therefore, if the outside temp is in the high 60's or more, I idle.

My T600 doesn't have the little side vents, only the flip open high upper windows making it difficult to get cool air to the bottom of the bunk.

I will shut the truck off if it is between 45 and 65 degrees, this is comfy sleeping weather.

I think some of it involves sleeping comfortably in dead silence somewhere, and then having one of those guys pull up who idles all night, with an air drier going off every 20 seconds. Or being parked next to some a-hole that stats his truck up and revs the motor instead of just setting the cruise to 1000 RPM's to warm it up. My own truck idling will drown out the noise of most everything else if I'm in a deep sleep.
