Lots of drilling and tearing up the walls in this thread.... I use those 3M Contact strips for just about everything, in the TT and at home. I've never had any fail on me and doesn't mess up the walls.
I did try to mount a paper towel holder in the Outdoor Kitchen of my TT with those and I'm guessing the leverage of it sticking out and lookiing back I should have taken the towels off while traveling, but it made the wall paper seperate a little, I removed the strips and smoothed the paper back down, all is good now. I remounted it under the cabinet with the strips and has been there ever since.
