I think Mt Cammerer firetower is on the west side of the ridge. Not sure if you could see a sunrise from there, maybe a sunset. Also, just so you know, camping at the firetower isn't allowed. So if you wanna catch the sunrise/sunset, give yourself enough time to get there from your campsite or shelter.
I've been to Mt Cammerer once. Weather was okay in Knoxville, but we passed through heavy rain as we approached the Park. At the trailhead, the air was still wet and very foggy, so I decided against taking my camera. Hiked up the hill in lingering drizzle. When we reached the firetower, clouds had lifted somewhat, the sun was shining from the west and absolutely lit up everything. It was dazzling. I had no camera.
