Just wanted to share my bad experience with the 3 M Command Strips. I know the ads all say will work safely on all surfaces. Not true! I have hung everything in our 369 RL with various sizes of these because I didn't want to make holes in the walls. I had a small canvas picture fall off the bedroom wall. It is very light weight and the strip I hung was rated for much more weight. The bad part is it bubbled up and ripped the wall paper when the whole thing fell. It looks to me like the command strips are pulling the moisture/glue out of the wall covering that is on the inside of all of our coaches. I manually took the other one down that is beside the one that fell and it also was bubbled underneath the strip. I am now in the process of taking all of them down and using screws or nails. They may be permanent but at least they will leave the wallcovering on the wall.
Very upset with Command strips!
