LP storage advice please?

The collection was in my parents' FL condo for 30+ years. Pop had them on some cheap graybar shelving. When I packed them, I made sure the boxes were snuggly packed so they wouldn't shift, lean or sag. 

I plan on using the Kallax system in our next home as the storage solution. The thought however of doing that in a storage unit somehow doesn't seem practical.

Thank you all for your thoughts.

Happy listening.

Florida. Check for mold.

costco shelving, mine was Gorilla brand…..

Use the black totes with yellow lids or the larger black totes with red lids (with or without wheels) from the big box hardware stores. We use them for theatre lights storage 4 high, and they are heavy. After moving the LPs to your new place, you can still use the totes for other storage.

Good advice given. 
Pay attention to MOLD. No moisture, humidity. Once mold starts, it will spread. 
 IKEA shelves are excellent. If you set them up in a storage unit, you can easily disassemble and use them somewhere else. If you’re inclined, Craigslist is a good source for used IKEA shelves. If they’re used in a storage unit, who cares if they’re beat up.
