Tips for unplanned move to fulltiming over the next months?

I am losing my job at the end of the month. Suits me fine; it was a bad fit and my wife and kids have the whole summer off. So I won't be looking for something else before september.

Got the truck last year. Got the RV last week(originally planned for a 3 week vacation).

What are the things that are needed for fulltiming but not for 2-3 weeks that I am sure I am forgetting?

No solid plan but aiming for Moab and we'll see where we actually end up.
