I totally understand. I grew up off-grid and don't like to rely on anything that requires a signal.
I carry my USGS topo maps in my truck at all times. I also carry an old, out-of-service smart phone with Avenza and other apps and my digital maps.
The maps and app, once installed, don't require anything other than a GPS signal (and a charged battery) to work and even the GPS signal is optional (signal loss means you use the geoPDF map as you would a paper map albeit with a much smaller viewing area). The paper maps don't require anything other than a knowledge of how to use them and a compass if necessary.
Both have their uses, neither is infallible.
For a long time we carried a pilot's case full of maps and MVUMs and a few key guidebooks. But it got unruly and I have/had to continuously rotate what was in there to have the right mix of references for any particular place we might want to explore. We usually have all the Trails Illustrated maps for CO and bordering areas in WY and UT. I would keep the CO, UT, WY, NM and AZ Delorme Gazetteers.
But seriously, all this fits on a 32 GB SD card now you can stick in the glovebox. The printed Gazetteers still come because I don't want to spend money replacing what I already have. When we're out exploring roads and trails (which is getting harder to do since every agency seems intent on signing and directing every mode of travel anyway) we figure it out just as often digitally as using old printed references.
I do still buy printed Trails Illustrated maps and atlases periodically. It's mostly as targeted back up incase of dead batteries or electronics failing than as primary navigation to be honest. I don't really get paper copies of USGS maps anymore, just digital topos with OSM data compiled in on a dedicated device or an old phone.
I'll build a track and lay in a few waypoints to somewhere that looks interesting, which is what we follow instead of a written or highlighted route. It's just an adaptation of how we've always done it. When I leave the track I
thought would work I can always follow the breadcrumbs back if the explored route doesn't work out. If the new field followed one does work then I have a good record of how I got there for the future.
