I'll agree in general with the no more than 30 seconds warmup. Under reasonable weather. However at least some of the newer diesels WILL warm up when cold with a short idle time. My 2015 duramax with temps near 10F will start nice hot air to the cabin in 5 minutes from a cold start while idling. How?? well, one they bump the idle speed to around 1000rpm, second they run the turbo vanes to maximum backpressure. now the engine isn't just a air pump, it is actually needing to do some work. So, normally get in start and drive. when below about 20F I hit the remote start, let it run the 5 minutes or so it will do with the remote start, then get in and go. Oh, BTW GM is nice enough to also have the heated seats on while it is under remote start.
Wonderfull.

OP here, The DPF is my concern, but I do pull the boat to the lake, or take the camper out at least once a month, and we run to ATL, or Birmingham regularly, so I do get on the highway.
About how often do they want to Regen? I've read it's determined by soot particles, but does that equate to 500-600 miles? 2000 miles?
I drive about 15000 miles a year.
No engine (gas or diesel) likes short runs but as long as it gets an occasional run long enough to get to full operating temp, it's not a big issue.
If you are taking the camper out once a month and doing a couple runs per month to Atlanta/Birmingham, that will satisfy the need to get it up to temp and regen.
As far as warm up when you start, anything more than 30 seconds is a waste. Diesel engines take so little fuel to idle that they will never warm up in the driveway. Best to get on the road and not stomp on the throttle for the first 5 minutes of driving. FYI: This is what the manufacturers recommend).

I'm considering a 2015 Duramax that a friend is selling that is pristine and well maintained. He drives a lot, it already has 115,000 miles on it.
I on the other hand have a short commute only 6 miles each way. I keep reading that short runs are rough on the new diesels because they don't get up to temp. Would my short commute be to short to warm it up good?
I live south of Atlanta, so in the winter, it's not like it will be really cold in the mornings. Not sure if that really matters.

Some of us "armchair automotive engineers" own and operate DPF equipped diesels so we have lived with their requirements.

My plan/thought/debate on this truck is as follows. I've got a 8000lb TT, still in gasser range, but in the mountains of N GA, and NC, the power would be nice. Currently I have a 2002 Chevy 1500HD that I bought new, and now has 209,000 miles. I was thinking of passing it to my 14 year old in 18 months when he is 16, and buying something new then. My buddy has the Duramax, and he travels the southeast for work, and has put 115k on it in 3 years. He is anal about his vehicles, and it is spotless, and has had all the maintenance done on it. He will sell it to me for what they offer him on trade.
I'm thinking with the low miles I put on it, I can drive it for 8-10 years, and only be at 200-250k miles. At that point both of my kids will be out of college and the house. At that point we can buy a Class A, and a Jeep as a toad ๐
