Welcome!
As far as cleaning the soot, not I have not. We have a few threads around here about an additional oil filters, search around and you'll find plenty of info and opinions.
As far as towing more.. just don't risk it. Likely the truck can handle it, but if you ever had a wreck and cause...
Good to hear they have a little common sense!
I always like to test the 4x4 when I get a new truck, because like you said, you never know. Luckily I've never had that problem.
Sorry to hear. Glad you had a fire extinguisher nearby as it could have got the travel trailer as well. As long as everyone is safe is all that matters.
I wonder how insurance will handle this one? Since it looks like it's pretty contained to one area.
Welcome to the site!
Welcome.. I'm not a fan of modules like that. I've never come across anyone that actually said it helped. Go with a true tune from guys like GDE, PPEI, etc.

Well, that's a little scary.
Welcome! Hopefully the light is nothing major.. once you get the codes and/or a fix, post back as it could help anyone that might have had the same problem!
