Sorry - neither steering your towards nor away from the Highland. I don't have one, so I can't make comments from experience.
I do have the Fox River, which is just a tad larger. It is an excellent hunting knife, and a good camping knife. To the degree that they resemble each other, I'd say they (or the Highland specifically) make better hunting knives than camping knives. After all, it's what they were designed for!
I think either the Canadian Special or the Kephart would be better for a primary camping knife.
I think the ulimate triple threat would be your Mini-Canadian for taking game apart and other smallish chores, a Canadian Special for general work, and a Golok for chopping, batoning, clearing, etc.
