People change - no need to beat yourself up about it.
I have gone back and forth between unsupported solo camping, car camping, and RVs. All of them have their pluses and minuses.
I do find that if I finish off a trip with a few days somewhere that I can get a hot shower that it makes the whole trip better.
You probably already have too many obligations in your life, so no need to feel obligated to camp a certain way to stay true to some ideal you formed years ago.
My two cents anyway.
