There is an excellent resource located at the DICOR website. It's called, "Rudy's Expert Roof Care Handbook" and should be "required reading" for every RV owner. You can download it here:
https://dicorproducts.com/images/RudysRoofbook_16.pdf Look at page 10 in the handbook for a specific process to use in determining if your roof is EPDM or TPO.
Note: TPO came on the RV scene around 2010 and the gradual process of converting from EPDM to TPO occurred during 2011-2013. After 2014, only a few trailers were produced with EPDM roofing. Today's trailer roof membranes (from about 2017 forward) are almost exclusively TPO.
Follow the guidebook and you'll be "taking good care of your roof"....
