I have reconsidered work camping and would be open to it a few times a year when I need to slow down, but will probably consider it as a last resort measure only.
Some RV parks and campgrounds where folks purchase the site for exclusive use hire full timers, give them free space while working there, and pay a nominal hourly wage. You can live for almost free usually as the pay is often enough to cover food. And as others have indicated there can be lots of exploring on the days off. It helps your money stretch and is rarely looked at as 'work'. And if you can't stand it, quit. You have nothing to lose, a real win win situation.
