Wow you hit the lottery and didn't even have to buy a ticket. I would only take what I thought I could use unless he wants someone to take it all and distribute it accordingly. He may be overwhemed by the whole process so he may really want some help. I would listen to him and do what you think will be what he needs. Also you can go through the piles and donate what you don't need if it will help. I agree with those that say, if you don't need it, don't store it, let someone use it that can.
