First time seeing this. guess I need to check around forum more.
I think my best prepping was 29 years ago when we paid off the house. We have never borrowed against it. Then in 2013 we had to buy a new car as the van blew it’s second engine. That was one big lemon. the payments were set up for 76 months and that was way to long. it took everything I had but got it payed off in 24 months. That was a big relieve. Other than that the best purchase we have made first was the whole house generator. It is duel, so can run on either natural gas or propane. We have it on natural gas right now. I think then it would be the big berkey and I have bought over the years about 10 filters for it as they went on sell. Then maybe the grain mill. I have been trying to stock both red and white wheat that I have to grind into flour for bread. Non electric and works great. Other than those things right now, it is all I can think of at the moment..
