Recently purchased a 2018 Ram 3500 Laramie CC SRW Cummins Turbo with Aisin tranny. Love the truck but trying to understand the Turbo cool down guidelines. Sorry if this question has been asked before but here goes. If I follow the diesel supplement chart, I should idle anywhere from 1 to 5 minutes depending on Turbo temp (cool, warm, hot?) before shut down. Do the recommended idle times apply when stopping to fuel up, etc. I will be towing a 5’er. Any suggestions or advise are much appreciated.
