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.
