THANK YOU for all the great comments. One thing I like about camping is working on projects on the TT. Went into town and checked out the wire shelving, and based on the comments here, we decided to go with 3M Command Strip Hooks. Nothing to screw or drill.
Here's the space before I started. (Glad I brought along my work light!!)

Getting the 3M Command Strip Hooks installed

Done!!

And then with all my clothes. (My wife will be HORRIFIED that I showed you all this one!!) :)

Bottom line: I love it!! Looks and works great! Thanks again for the tips!
