Gun safe for RV

I pored over this when we began full-timing 2 years ago We sometimes deploy the porch and I did not want anything in the garage that looked like a safe, and I came to realize that a real safe is just not an option, so I opted to give my 2 sons all but 4 of my guns. I get to shoot the ones gifted once or twice a year when we visit them. I have found several places in our rig to conceal weapons/ammo and do so. I carry daily, so there's only 3 left in the rig any time we're gone. Of course when we're in states that my LTC/CHL doesn't apply, I have them all secured. The OPSEC is the main thing in my mind. There are no stickers on the rig, truck or motorcycle, and I don't own or wear any shirts to make one think I might own weapons.
