I think this is a common problem, and I think it's just that sometimes there aren't enough possible camp locations in a particular area for everyone at once, as it affects me mostly in areas with a lot of through-traffic and a higher online population (e.g The Heartlands, Great Plains). However, if I go for a two day hunting trip up at Brandywine Drop, camp set-up is immediate as it's so remote, so much so that if I don't like the area it drops in Roanoke, I just change camp to another region, then change back again to get another Roanoke camp location, and repeat this until I get the one I prefer.
