To Engine Idle or Not
William Brosam:
if its at night its to heat /cool power the living quarters or refridgerator unit.
if you pull into a rest stop after driving in high ehat or a mountain. and kill the motor what happens is you trap the oil, and water in the motor in the hottest locations and dont allow it to flow and keep all parts within the workign temperature, instead it has to cool by soaking and drawing the heat though the passageways which doesn't work as well.
a few minutues with the fan blowing, water pump running and oil pump chugging away usually has things cooled down enough.
if its extremely cold most never shut the diesels off as they may not start, but i doubt you will be RVing in -20*F or colder temps

One CAT document I read said that the necessary cool-down was on the order of ~3 minutes in order to cool the turbo sufficiently. A comment was made that usually by the time you turn off the interstate to get into a truck stop you've probably been going slowly enough for long enough to be able to shut it down without further waiting. The only time this isn't necessarily the case is when we pull directly off an interstate into a rest stop. In those cases I usually let it idle for a few minutes.

I usually perform the same thing with gas motors, ie lawn mowers, chain saws, etc. in allowing them to idle a little before shutting them off. Thanks for all your advise and opinions!
