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.
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.
