I would like to claim credit for this idea but I saw it when looking at some vintage trailer pics on the Internet
I used metal tip trays. Of course if you have a larger RV you could use those small TV trays.
I then used the
removable hanging strips to mount the trays to the wall
I hot clued super strength magnets to the bottom of my spice containers (I got these at craft dept. of Wally World and they are quite small)
And
voilą!

You can also purchase different types of
metal spice container racks and
separate metal spice containers
I may order some of the smaller metal containers ones later...
