Renal

Do any of you suffer from renal failure, ie, having to use dialsys.  My OH as yet does not need it, but he's attended a pre-analysis clinic and the sort of dialysis he can use.  One of them is the set-up at home, and of course, we want what is best to go caravanning.  Is anyone on dialysis, and do you need to arrange to have the bags of fluid delivered to the relevant caravan site.  If so, are there any problems?
