Replace Thedford Aria Deluxe I with Dometic Revolution 320?

Has anyone made this switch? From the footnotes on the Sealand toilet, since the Aria has angled bolts, it appears a Sealand mounting adapter is needed. Curious if anyone has confirmed that is the case and if there are any things to watch out for in that regard. Any other words of wisdom appreciated as well.

From what few reviews I saw on the Sealand toilet itself, folks sure seem pleased.
