Kiwix can take up a huge chunk of disk space for its archives, but what self-respecting geek doesn't have a multi-terabyte home server nowadays? I've had Wikipedia and Gutenberg set up on it for a while.
Another offline map option available for Android is Magic Earth. It's the only non-free(-as-in-speech) app bundled with /e/ because they've not (as of last time I checked) found anything better that was free. TBH, it does a pretty good job getting me around, especially in areas where cellular service is spotty (as it frequently is in the less-populated areas out west). Their map data comes from OpenStreetMap.
Another offline map solution (also built from OSM data) is this ~1 GB Kiwix ZIM file on Gumroad - https://anthonykaram.gumroad.com/l/offline_world_map
Just try mapy.cz for Android. Offline maps, offline navigation, recording tracks... Available with OSM and has tourist and cycle maps.

Not having paper maps maybe won't be a problem, unless you plan to walk.
Gas pumps (and electric cars) probably won't work without the Internet.
