I use the Condor Pit-Stop and stop side to side with straps to factory floor points; up front in the bay. I have a roll around island cabinet that is pretty heavy; I strap it down by running a ratchet strap over its top, again to factory floor tie-downs; and it doesn't move.
If the walls of your TH are similar to mine, the so called aluminum frame material, is a little more than twice a beer can thick. Consider you have essentially approximately 1-inch of Styrofoam sandwiched between 1/4" plywood and very thin fiberglass skin. To get any strength from the wall you would have drill the wall and bolt through it, with a plate on the outside, something no one should consider. I am sure any wall related issues would not be covered by warranty, when FR sees what was done.
If I felt the need to hold things to the wall (like a ladder, etc.), I would build a rack and would bolt into or strap to the floor, with it mounted close to the wall.
