Cummins 400 ISL diesel particulate filter
I am getting a new to me 2007 Itasca Horizon DP with the 8.9 Cummins ISL 400hp engine. The EPA 2007 rules required a diesel particulate filter. Was that a requirement on 2008 model year or 2007 engine...

Presumably you're asking if your new-to-you coach has a DPF? As stated above, Cummins should be able to tell you, as could Itasca/Winnebago if you call there with the VIN.
We have a DPF on our 2014 and have had no problems with it (and hopefully it will stay that way). There was discussion of a poorly-manufactured DPFs cracking and I'm sure you can find that information by Goggling it. Mostly I've read about that happening on Tiffin Breezes, but I don't really pay attention on what other manufacturers might have been effected.
Idling isn't a huge issue unless you do it for a long time and the system isn't able to do a regen and burn the soot ouf of the DPF when it needs to. You need to take it up to highway speeds so it can do that.
Congrats on your new Itasca.
