On the other side of this I use RVreview (or whatever it s called now) Google and a phone call. All of our trips yearly across the US are preplanned and we have stayed in many of the same parks each year but we do add some also. If you look to where you want to end up at the end of the day (our day ends around 5:00 or so deepening how far I care to drive. We stay hooked up relax, do dinner and then read a book for a couple hours. I know the park from Google looking overhead, no surprises. We leave normally at 5 in the morning, we are on the road in 15 minutes. Works for us and as said helps the locals out with a few bucks they are there for us overnighters.
