Welcome to Arizona and thank you for taking the time to research your questions! I'll try and answer the general gun toting questions. As far as the outdoors and camping stuff, it's something I don't do.
I recommend purchasing the Arizona Gun Owner's Guide .
Be aware that if you are on Indian Reservations, Arizona state gun laws do not apply and tribal laws rule. Most ban at least the carrying of guns.
You do NOT have to keep your gun in the glove compartment. For 21 and over, there are generally no restrictions on where or how the gun is carried, open or discreetly, on your person or in a vehicle (exceptions involve schools, places that serve alcohol, government owned buildings, etc.).
Also, in Arizona law there is no distinction between a loaded and unloaded gun. Load your pistol and put one in the chamber.
ARS 13-3102 is the law on "misconduct" with a weapon that covers most of what you are talking about. Be aware that the law does not "grant" diddly-squat. It just tells you what you legally cannot do.
Other sections also cover self-defense, threat, intimidation, assualt, etc. The stuff that happens or can happen to you, if you use your gun. Basic rule - if it's not worth dying for, it's not worth shooting for.
You CAN legally do all of the above. From a practical perspecitve, a gun that is not within reach (preferably worn in a holster) is useless.Stuff I should NOT do:
1. I should NOT stuff the gun inside the side of the door in the truck (storage area).
2. I should NOT keep the gun stuffed under the seat.
3. I should NOT keep the gun hidden anywhere near me that's not the glove compartment or my hip in a holster.
That's the same as not owning a gun. Might as well stay in CaliforniaI feel like just locking my gun up in a container the whole trip but then again, why should I?
You're in Arizona - exericse you right to bear arms and smell the freedom.
