My Son shoots Sporting Clays all over the US.He has a built in safe in his truck bed with sliding drawers.The safe has its own power source and alarm system.The lock is coded and there no visible ways to pry the drawers open.He has an electronic lock down on the engine so only he can start it.This is well designed system ,but it is not cheap.When you consider how much he has invested in shotguns and ammo,it is well worth the cost.I don`t remember the systems name,but will try and find out.

Its all right to be white!!
Stupidity left unattended will run rampant
Don't argue with stupid people, They will drag you down to their level and then win by experience
