Full-time cancer treatment

My husband Christopher was diagnosed with cancer(synovial sarcoma) in 2014.  He had a large tumor removed from his thigh and underwent 6 weeks of radiation. Now, with extensive nerve damage he can no longer work as a carpenter as he had for the last 10 years or so. Thankfully, he had short term disability. (Aflac) However, this has long run out. We have a little girl, Ana who is now 2. Until my husbands next MRI, the doctors tell us it's not clear if he will need further treatment. The waitingis  unbearable.
   Without knowing how much time we have left with my husband, we have changed our plans. Chris would like to spend what time he's got with his family, seeing the country. Since getting the cancer, Chris has a passion with all things mushrooms. Apperently they have incredible healing properties. We would love to follow the seasons in search of medicinal fungi. We have a good truck and with the help of family, now we have a good travel trailer camper. It is our dream to go full time as soon as we can, but now have hardly the money for rent. Please help to get us going.
