Each has its place. Full hookups are nice, but if you are properly equipped and know how to dry-camp, that opens up a lot of possibilities otherwise unavailable.
We've dry-camped for as long as 14 dwys straight, utilizing 300w of solar into a big battery bank, occasional generator use, a blue tote, and a 40-gallon water bladder for refills. Lots of beautiful state and national park opportunities available if you can dry-camp. Add in a few NA$CAR races, which also require dry-camping....
