We left FL at the end of Apr, traveled to Missouri the across to Utah and now we are at Helena MT. No problems finding sites but commercial parks have ramped up their prices. What used to be an average of 30-40/night is often 50-60/night now. You can stll find lower prices but you will have to look harder.
We do use a mix of commecial, Fed parks, State Parks, Famcamps and Boondocking.
Major NPS parks have to be reserved months in advance as always. So they are not on our list for the most part.
We have found that many more USFS camps have First Come sites than we expected.
Unhappily our fav YNP BLM dry camping park was flooded and not returned to operation by the BLM. But we found a USFA park in Island Park this year.
