Since you are living on the road, I don't have any ideas for what to do with her body, other than cremation seems like the best way to keep her with you in a way. I did hospice with my Misha (my avatar) at home. Our vet called in a Rx for morphine and I administered it according to her directions. I feel it was the best way. She was at home with her loved ones. I couldn't bear taking her to the vet to be put down. I felt she deserved to die as people do (I've observed that there is something holy about the dying process), as she was a person to me, and I didn't feel it would be right to interfere with the natural process. I laid on the living room floor with her and held her in my arms during her last 24 hours. The cats knew what was going on and each of them went up to her individually and said their goodbyes. She is buried in our back yard, along with two of our cats.
