Location: When in the Newell it changes. Home: Oregon
Ideally parks that have paved sites are what we like. But if the area we are in doesn't have a RV park with paved roads and spots we will still stop and stay. Most of the time we do our research first so we know what to expect for the most part anyway. You know there are always surprises with traveling.
If it's easy to find, easy in and out, that makes for easy traveling. If it's an overnight stay like Chester said we aren't too picky. But if we plan on staying a while we like the RV Parks and Resorts that are paved and well landscaped.
