But I could have two crony/NTP servers no? In addition to box10 I could make box7 an ntp server and list both in the clients configuration file? That doesn't seem problematic or am I missing something?

Yes, you can have multiple "server" lines in the config file. And, if you want, you can use the FQDN and configure your DNS to serve IP addresses in a round-robin fashion.
With the following config.:
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server 192.168.1.10
# server 0.rhel.pool.ntp.org iburst
# server 1.rhel.pool.ntp.org iburst
# server 2.rhel.pool.ntp.org iburst
# server 3.rhel.pool.ntp.org iburst
I see:
[root@box48 bobg]# chronyc sources
210 Number of sources = 1
MS Name/IP address Stratum Poll Reach LastRx Last sample
===============================================================================
^? box10 0 6 0 10y +0ns[ +0ns]
+/- 0ns
Which looks like it's not working? The "?" must mean something?
I've tried disabling firewalld and selinux, neither appears to be
causing a problem.
I've done:
systemctl restart chronyd.service
and then:
[root@box48 bobg]# systemctl status chronyd.service

And I still can't tell from any of this if it's working. I'm in over my
head here ...
