So sorry to hear this.
My father was an avid camper...where I got my camping gene from. He was prepping for a big trip in his new 5th wheel, and then found out he had stage 4 brain cancer. After surgery and healing, and right before chemo / rad, our family loaded him and his trailer and did 2 nites locally. So sad...he could no longer drive, had to have help with everything (I mean EVERYTHING) but the pics we took and the smiles he had on his last camping trip were great...
Enjoy life while you can. I hope all turns out for you.
