It depends. I play on persistent servers so my tent doesn't despawn due to server restarts and they hold a lot of gear (63 in camping tents<--blue<-- and I can't remember how much in military tents. I use camping tents a lot for multiple reasons: A.) To store food and supplies in a secure location. B.) As a safe place to hide if you need to nip to the loo or get food. C.) To bait other players if I feel like saying hi to someone new. It isn't such a good idea to hide guns in a tent because if your tent had items stolen from it, guns would be stolen or hidden are much more valuable and can be used against you. I advise using them to store food, medical supplies and some ammo, plus extra clothing if yours gets ruined. These items can not only be used to support and sustain your own life and adventure in dayz, you can use it to help fresh spawns and those in need if you are feeling kind. Tents are very useful and I love them. It also depends on your play style so think about that when looking for one. They are a portable equivalent to bases in dayz and when base building arrives in dayz I will still use tents. Be carful where you place your tent so it is not easily found and stolen from and they are pretty much pointless on non-persistent servers but hey, it's a tent, it's freakin awesome! To sum up, yes they are worth it. :)
