I was going to look into using HHD for my father at one time and did a lot of research several years ago. He passed away before I could get him to travel with us in the motorhome but it still interested us a bit as I may be on the verge of needing dialysis. However, we ultimately decided to give up RVing awhile ago.
You've probably heard of Harvey Wells? If not, watch the video below and it will give you some insight. It was back in 2012 and I do know there have been a few advancements in HHD machines since then. I was looking at that SC+ with some interest when it came out (
HERE) but still not FDA approved for use in the U.S.
I too wish you the best with it. After conferring with your nephrologist and getting the proper advice, don't let it get in the way of traveling in a motorhome if that's what you really want to do. Safe travels always.
