So, I am about to get my first diesel truck. In the "olden days" diesel engines were left to idle for long periods in order to not cycle them off and on unnecessarily. But in reading this Forum recently, it appears that idling the newer diesel engines is not good for them. I can see an example in my case where I am going to be using my truck for towing a travel trailer, when hooking up before a trip and also when setting up at a campground, that I could be idling the engine for quite a few minutes. So, is it better to stop and start the engine two or three times or just let it idle for 10 to 15 minutes? Thank you!!
