Welcome to the thread, glad you stopped in and hope you will continue to add your thoughts.
Your addition are good ones, and a roll of toilet paper fits nicely on a shovel handle.
In the city, one might add one of the small metal sheds in a corner of the yard, with a dirt floor, LOL, you know a tool shed to store the shovel in.
I forget that everyone does not own an axe and shovel.
For years I had a folding military type shovel in the truck, but someone took it.
I would want a couple rolls of the drop cloth plastic that Walmart sells, good under and over sleeping bags and to seal things, to keep the rain out.
For me, I would also want Essential Oils, Lavender for many uses and Oregano as it kills bacteria and other bad guys.
The citrus family also kill germs.
LOL, Bill hated it when I packed the camper and I could not stop from laughing, when he wanted something that he did not want in the camper......but he knew I had put in there.
I found some wonderful soft baling wire at an old mine camp, and started rolling it up, he said “you are not going to put that in the camper”, which I did.
The next morning when we went to leave, the truck had lost a cotter pin and would not work, so he had to ask for the hiding place of the baling wire and use it to come out of the far out area we were in.
Another time the distributor cap kept breaking that little metal arm that was in it and he would replace it, then one night in the middle of a bad rain storm, it happened again, and he put it back in place, used a band-aid that was in my purse.
So it is true one never knows what one will need next.
You are welcome on this thread and I hope you will continue to share your ideas.
I’d also like to add: scraps of fabric for the ladies’ toilet needs. TP would be precious and should only be used for #2. Homemade napkins would be most welcome.
Then there’s this option: http://www.mooncup.co.uk/
I have one and it works just fine after you get the hang of things. :-)
