Attaching Items to Walls ??? - Event Date: 29 Mar 2020 - 29 Jun 2020

I'd suggest that you take a look at an rPod construction video before attaching stuff to your interior walls. It will help you to better visualize what you have in there. You have a pretty thin luan layer with foam insulation behind that. It would be hard to get an expansion anchor to expand into the closed cell foam.  If you are attaching to the side walls and can find the 1 inch square aluminum tubes then you can probably attach something that weighs 10 lbs or more, but if you're just into the luan or in the curved roof areas which don't have aluminum tubing then not so much. 

+1 geewizard we use velcro command strips and we have even used it on a large cribbage board, after I take it off the wall and my wife beats me in a game of cribbage I can then hang it back up on the wall as a piece of folk art the command strips work well

I've had Command stuff fall off walls before. Seems like it adheres well initially but once its there for few months it often seems to fail.  I suspect humidity causes it but don't know for sure. One good thing is that the hangers came off clean and didn't mar the wall finish. Can't say the same for the stuff that fell down though.

Good question.  I haven't tried a stud finder. The side walls have aluminum square tubing so I'm not sure a magnetometer based detector will find that. The old school stud finders with the magnets in them wouldn't. The new imaging ones ought to work.
