We always have a computer with us to download camera pictures and I put all the trailer manuals on a thumb drive hat I leave in the camper so if something happens that I can't get on the internet I have the manuals. There are places that my cell phone comes up with no service. It was either that or print out the 10 or so manuals that go with our trailer. In this case smaller is always better.
Think about things before you do them make life easier not harder.
