Yes we have found that most things are not hard to replace and so far I’ve ordered everything from Amazon except the micro wave. The water heater is about the only other thing we are concerned about. So far its fine. The furnace and AC work great but we hardly ever use them. We use a couple of electric heaters and we bought one of those portable air conditioners last summer. It cools the place down fine and pulls about 35% less watts and is pretty quiet.
I have the water heater out of the Gulfstream now.... Part of what I was talking about in the original post... It has a manifold next to it that has both cold water flowing in and hot water flowing out... the manifold failed, internally and externally when the water heater went, and apparently is irreplaceable; I’m going to have to bypass the manifold, run independent direct lines, with regular Tees instead of complex manifolds; input to the water heater and then out to the faucets etc.
