I would not trust any location unless the items are also secured with a heavy duty safe of some sort, and that's contrary to the weight savings we all need/want.... but....
...have you looked at that thin carpeted floor of your wardrobe and, using a thin blade, lifted up the wardrobe floor? (Not sure you have anything similar to the wardrobe in the 22' Sport models...but thought I'd mention it.)
A "decoy" is also an idea perhaps worth exploring. (The immigrant travelling across the W. Texas prairie that stole the 30-30 in the remote ranch house is in for a bit of a surprise when he finds out the firing pin is too short to reach the primer and is an obsolete part. I bought it at a junk yard for a wall-hanger/decoy. The thief stopped looking after he found it and completely missed the gun collection beneath the false floor of the cabinet....but NCIS now has the serial number in case he's discovered with it.)
(This decoy idea is a trick I learned from an old Naval Aviator, Will Kilgore, on a trip with him to Mexico back in the '70's. He always carried a wad of $1 bills in his pocket, which appeared to be a lot of money but was less than $20 total. He recommended I do the same and it seemed like a good idea... and 15 years later actually paid off.
While crossing the bridge back to El Paso I came across a young lady who was struggling with a group of young hoodlums trying to take her purse from her. It was beginning to look ugly. I got their attention by throwing the wad
of one$ to the wind and shouting at her to run-across the bridge with me.
It worked. The group all dashed after and fought over the scattering one$ and she and I got across to the U.S. side without further trouble.
Old Navy Guys don't get old by being stoopid.)
