LZ0 Duramax Decision - Input Requested

[StephenPT]

I appreciate everybody's input, lots of good info. On the dealer warranty - I understand the potential gotcha's there. I'm not seriously considering it just because of the fuel economy of the 6.2L, but if I did I'd comb every line in the document. I'm that guy that annoys the sales/finance team because I actually read what I sign.

One other question, regarding regen. Since this thing would be used by the wife for a lot of short (5-15) minute trips around town, am I going to potentially run into issues with the regen process? I hear people say to just drive it like a gasser but I'm not sure if that's actually the case.

A full regen process takes ~12min. I have a Banks IDash installed to know when it's doing a regen in addition to watching other things like oil temp, boost psi, etc. While we mainly use ours for long family trips and it rarely does short in-town trips, there's been a few times where it wants to regen, but we need to turn it off and then the next trip is a short trip to town. The system is designed to regen as much as possible each drive to lower the soot load and get it down to ~0%. If there's too many short trips and it's not making much progress on the soot load with each trip, you'll get a notification to "continue driving to clean exhaust system." I've never had that happen personally, but I've seen others have received that message.
