Google says to submit both domains with and without www. 
Do I create a new sitemap for each version of my domain?
If so, how do I do that?

Hello, 

in this case I would recommend to run generator in command line if you have ssh access to your server.

[XML-Sitemaps Support]

The command line to be use in ssh can be found on the Crawling page of sitemap generator, example:

Code Select Expand
