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.
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 :)
