I recently took delivery of a leftover '20 XLT with the 3.0 PS. I've unable to find a recommended idle time to let the turbo cool prior to shutdown. Any suggestions? I'm also wondering why the auto stop/start is included as standard equipment when the owners manual specifies a cooling period before shutdown, I have ordered a module from Western Diesel that defaults the system to off at startup rather than having to push the button each start.

Chief, I went through the same thought processes you did and came to the same conclusions. I bought the auto start stop disabling module (love it) and I just do short cool downs as needed. The exception was summer camper pulling on the interstate when quickly pulling into a rest stop, I feel a long cool down is warranted.
Just puttering around town and pulling into the garage may not be a big issue. Our modern full or semi synthetic oils minimize the need for the old fashioned extended cool down in my opinion.

The owner's manual for my Ram gives different "cool down" times, depending upon use. As Dunrollin suggests, if you have been towing Ram says as long as 5 minutes. Typically a minute or less. Not a fan of auto start stop, especially on a diesel. As a builder of commercial work boats, I see owners that give their diesels a little time to warm up and cool down time have much better longevity than the "hammer down guys".

Unless towing, I’d not even consider messing with turbo cool down. After a few million miles, I’ve never had an issue with turbos on trucks for driving interstate or rural from not cooling it down. Now, running loaded, or semi-loaded on the interstate at high speed, I let them all cool five minutes. Sometimes I wonder if a turbo timer is something I should get, just because when traveling, no one wants to sit in the truck while it cools down. Maybe I’ll look into one.
I have a 2018 3.0 PS and can’t find anything in the manual regarding a turbo cool down period. Where did you see that information in the manual?
Page 188 in the 2020 manual.
$44K from a dealer in Salina, KS. Couldn't find one in MO anywhere near that price.
