As others have said, years of camping, nothing missing. If a determined thief, not a meth head, wants your stuff or your camper, there’s not much you can do about it. They will have the tools to make short shrift of any security measures.
For any valuables left in the camper, I have a hidey hole that would be missed unless the thief started to take the cabinets apart.
I leave the hatches unlocked as it would be easier to replace the stuff inside than the damage caused by a forced entry.
Don’t worry, be happy. Go enjoy your camper.
