When we were full-time RVers from 2007-2008, we did workamping - which included getting a nice stream side spot near the Pacific Crest Trail for three months and getting paid to do maintenance/camp hosting at campgrounds in Mammoth Lakes, California. We explored the area in our spare time (an hour or so each day and one day off a week).
Another job where we stayed in our RV was Christmas tree delivery in San Francisco (very good pay for a month but hard on our backs).
At another location where hubby was adding
solar panels to our rig, I contacted a temp agency and did clerical work for a week.
For a truly agile system, a website cannot be beat. I was able to develop one while doing the workamping jobs as well as any place off grid where we parked our RV, once we had our
solar power in place - we used a satellite Internet system. If you can keep sand out of your laptop and there's WiFi nearby, you can work on web stuff at the beach! Have also heard of folks being able to do this out of a boat...
