What are we storing Emergency Evacuation Items in after LA Fires such as Fam Pics / Docs?

Since the LA fires in Palisades and Eaton, I want to prepare my family for emergency evacuations better and create a way for them to easily carry or drag / roll out important items.

I am looking at getting a couple of these with a carabiner between them so I could drag 2 at a time to the car (as a female with a propensity towards throwing out spine lifting things).

Please honestly lmk if this idea sucks and what is better.
