New Owner, Humbly Looking for Guidance

Thanks. I'm on mopar #2 here. I have a 2000 Dodge Ram 4X4 Quad Cab, with the mighty Cummins and 6 speed manual, that has been in the fleet since 1999. I spec'd it out, ordered, and took delivery of it immediately after it's birth in St. Louis. A big blue sport trim model. I call it Babe, as in Paul Bunyan's Big Blue Ox. I get guys wanting to buy it weekly. It will remain with me until it is crashed, blows up or is stolen. I still love the big loud tank.
