A safe place for David

We moved here to Oregon to help my sister with medical issues, three years ago ..But who knew we would be the ones who would need help. We are staying on her land in a very old and leaky 16ft. Travel trailer simi off grid, My beloved husband who has worked hard his whole life hows just found out he has stage 4 cancer and its untreatable. He is 61 and now cant walk at all and wheelchairs are impossible. .Im 69 and cant take care of him in this winter we'really need a safe and warm place with running hot water and a bathroom and a real bed.We were hoping to try and build something..but now i need help from above so i can keep him safe and clean and as happy as i can ...Id want and need a better and bigger trailer, one that can keep him warm and safe
Hes my whole life and the air i breath
Please if you could help in any way Im heartbroken we've been married 30 years. ...
