Helping my grandpa after hurricane devastation

My Grandpa has been living in an old school bus for about two years now. He used the last of his retirement to buy himself a nice camper to live in. After only having his camper for three weeks hurricane Zeta came through and a tree went right through his camper. Luckily he was safe and not hurt but as for his new camper, it is completely ruined. I am beyond devastated for this 80 yr old man who has worked his entire life that now has lost his home. Anything will help and be very much appreciated.
