2018 freedom traveler roof material?

[dsl]

I see everywhere on here that thor was using TPO through 2019. However with everything I see to distinguish TPO or EPDM I lean towards EPDM. I have only cualked as needed, roof has dull caulky look smooth texture. Unfortunately removing vent cover shows no excess roofing material. Any Ideas beside removing side molding?

TPO - it's like a plastic sheet.
EPDM is a rubber material and generally has a texture to it.

In my two trips through plant 750 (2016 and 2019) they were installing TPO roofls. The reasons given is TPO stretches allowing no wrinkles, it can be heat seamed and it reflects heat rather than absorbing heat.
