Hi @bgraysea,
Tehcnically speaking that particular rviz config file is tied to that particular URDF since your topics, links, etc will be different in your new robot but you can still use that rviz config by changing the sources of every plugin that you can see in the left panel.
Rviz is a visualization tool that works by adding displays to the interface. Hence you can start by launching an empty rviz config (E.g.: default) and then populate with displays by cliking in the left bottom button named "Add"
. Form there you will able to add odometry, tf, robot model displays etc. and then change your source inputs from each one of them in the left panel to adjust them to your robot.
There is a nice user guide that explains this in depth. Take a look here.
Hope that helps you.
Regards.
