The phrase "while camping" has a certain connotation to it.
Camping denotes more time spent in camp, less on trail
Hiking denotes more time spent on trail, and less in camp
Campers hike, and hikers camp. The difference is in the distribution of time spent doing each.
While i camp for the night, or make camp, am camped, was camped, was in camp, etc, I never say i " am camping ", thats a different activity. I am only eating and sleeping somewhere, not spending any significant time there.
" I went camping last weekend"
" I went hiking last weekend"
Two different statements.
Perhaps the term for what some hikers do might best be described as " bivouac" for the night. Bivouac denotes the temporary nature of the stop.
Then again, those hikers that hike 5 mpd, stop early and hang out in camp, bring folding chair, books, cook elaborate meals, extra changes of clothes, and I would tend to say might be getting closer to camping than hiking. Scouts often fall into this category.
