Please help my nephew

Please help my nephew. He was lighting the furnace in his camper, when it exploded. He has 2cnd and 3rd degree burns on his head and face and neck, and hands. He has no medical insurance, and is unemployed. The camper was his home, and he has lost everything. He has 2 beautiful daughters, that are lucky to still have their father. He was able to get out of the camper just in time. any help you could provide would be greatly appreciated.
Thank you in advance for your generosity!
