It all depends on the 'camp' job you're wanting.
If you're looking to be a camp attendant, then yes, you are perfectly qualified, even without a GED, to make beds, wash laundry, clean toilets, and babysit a bunch of men who act like morons when they're away from home.
If you're looking to be a camp cook, again, GED not really needed.
Those are really the two main jobs that are available in a camp. You should be fine for both. Or, you may be able to get on as a supply person, running back and forth to various camps with groceries and such. Check out the various camp management companies and send your resume.
Best of luck.
