The state of Minnesota has a newish website I learned about in another forum.
codeready.org Looks good. Not great, but it is probably the best I've seen to date by a state or federal agency. They also have a generator for shopping lists based on your household population and duration. Nothing on rolling gear, but most people bug in anyway.
And there is a joke- IIRC, isn't Minnesota the "North Star State"? Other states should follow.
