Sarah, we did the trip last November/December.

We went straight over in 3 days, and then took our time on the way back (via Texas and the SW). Perhaps you can get some ideas from our travels.
Splitting out the campground section is a GREAT idea, so I've implemented it. Check it out!
AllStays (Camp and RV) is a great app for finding campgrounds. One thing to be aware of said:I'd recommend All Stays too (if you're looking for a place for the night in unfamiliar territory).
