re: Which camping backpack should I buy?

I've never carried Mountain Apex but, carried Kelty when I was a poor college kid. It is a very good balance between quality and cost. Those are both massive packs and I am curious what your gear list looks like if in a 90+ liter pack, you're having to put the tent on the outside. It's obviously your choice on what you want to carry and bring with you, just please don't be one of those douchebags that is "in shape" so they bring everything they can think of and then leave lots of gear behind on the trail for everyone else to pack out.
