Hey Marsia, good to see you back!
Condolences for your mother, I know that has to be hard. You should take some consolation in knowing how much you did for her, right not that may be limited comfort, it will take time. I lost my mother about 10 years ago, hardly a day goes by that I don't think about her, but it is no longer a sad thing, but that takes time. Mothers are important.
Big Sur is a great place! I have not been for a while, reading your post reminded me of that. I also think of a camper van from time to time, but am concerned that I would not get enough use out of it to justify the cost. Good luck with your search, you live in a place where you could use one year round.
