So in a couple months my family(wife, kiddo, and myself)are taking my 2019 3500 dually on a road trip. Going from Pennsylvania to Wyoming to Colorado to Oklahoma back to Pennsylvania. Roughly 5000 miles. Leaving right before Christmas. Roughly 3 weeks.

Truck will have roughly 11k miles on it when I leave. Now I already changed the oil at 3k(rotella T6 15w 40). Thinking of changing oil again before I go but switching to T6 5w 40. Also thought about changing the fuel filters before the trip. However, thinking maybe I should just take the fuel filters along just in case they get clogged and really need changed.

Any one want to add their two cents on what they would do???

Also wondering what extra supplies would you take???
