Quite literally, someone who is happy doing what they're doing, or has just had a happy experience.
If you're not a happy camper, then you've just had a bad experience.
I went to sleep-away camp in the 1960's-1970's, and this was an old expression counselors used back then. They'd ask us kids, "Are you all happy campers?" to check with us that we were OK. It was a situational rhyme.

This term refers to a male wearing underwear (or pants) who has an erection (i.e., the tent pole). A man sporting a "tent in his pants" is assumed to be a "happy camper".

Makes perfect sense now, doesn't it?

The term Happy Camper originates from the quote, "Not a Happy Camper".

It has been in use for over 20 years.

It's origins are similar to that of the term "Touron" which is a cross between a tourist and a moron. These terms began and are currently widely used in the resort industry and National Park Service.

It was in use as early as 1986 Yosemite National Park by employees of the Yosemite Park and Curry Company.
