Get four wheel drive not just for the snow and mountains and beaches.
Get it because you also want to make sure you can get into and out of campsites and other areas that can be just a few feet off the pavement! I've had to pull off the road a few times onto greasy, wet, muddy soil to get around construction and accidents. And many beautiful campgrounds have unpaved sites. There are National, State and local parks with unpaved dirt sites that turn muddy at a drop of rain. We were outside Great Bend National Park two years ago and watched the entire campground turn to mud for a day after a rare thunderstorm. Only 4wd tow vehicles moved that day. If you go to a local winery near us they have only grass sites. The dry grass turns wet with any rain, and only 4wds will move for a day.
Then there are the tons of places that have loose and/or wet sand, stone, and inclines. We went to Chaco Canyon last year. It's not really that remote, but the last 20 miles are unpaved dirt roads with loose gravel, dust, ruts, washboard with washouts thru dry stream beds. It will take you over an hour in dry weather. But it's impassible in a 2wd if it rains as those dry stream beds turn wet.
Get four wheel drive. Only a 4wd allows you to confidently access the best camping country that isn't on a paved or well graded road.
