Thanks for the reply Ivan. I was able to mount `dom0:/dev/qubes_dom0/vm-...-private vmname` successfully, however when trying to mount `dom0:/dev/qubes_dom0/vm-...-root vmname`, I still get the `wrong fs type, bad option, bad superblock...` error.
I can confirm that I get this same error message when trying to mount any `--root` suffixed volume nested under `/dev/qubes_dom0`. To confirm, I am running Qubes v4.0. Any reason why the `--root` volumes in particular aren't mounting? Those are where `/etc/fstab` would be located, right? Thanks again for your help!
