I'm looking at an everything bag. Hold my shooting gear, hold my crap when I go on trips, SHTF pack, and also possibly for 3-4 day backpacking trips up the mountain. The one I'm looking at is dirt cheap, big enough, and has some good reviews, but my dad insists I'll be miserable backpacking without a frame. How important is a frame on a backpacking pack, and would a frame be a big detriment for other applications? This is what I'm looking at "advanced expeditionary pack"
