Not IT-wise, but there are still a few fire lookout/lighthouses that are manned. Look for jobs to maintain stuff like that. Rural electrical, microwave tower, pump station, pipeline survey, earthquake sensors, road snow plowing. Anywhere there are long stretches of infrastructure and low population. Live in a trailer.

Trucking industry is doing well for mobile loners.

Land surveyors in places like Alaska spend a lot of time with just their backpack, equipment and rifle. I think there are still jobs for population surveys, like counting penguins/birds.

Leidos would be another company that does Antartica, satellite grounstation stuff.
