Funny how things change over the years.
State parks here in pa used to not have any electric hook-ups and I always considered that "real" camping. Now a lot have electric and I love having that electric. No need to worry about how long you leave lights on inside and running the battery down. Some sites now have full hook ups. I've also tent camped, but don't sleep well in a tent anymore.
There's no right or wrong. Camping is all good regardless of your preferences. I like State park camping with electric only, best but that's just me
