Outfitter roof material?
What roof material did Outfitter put on their TC roofs in 2004? EDPM or TPO? Something else? I understand that there are different versions of Dicor caulk and one needs to get the right caulk for t...

We're 2005.5, and have TPO, not EPDM (like BlueGoat)
Off the Dicor website:
"Until recently, TPO production was protected by a patent ensuring a consistent chemical composition, however, that patent has expired. As companies raced to bring variations of TPO to market it has become clear that not all TPO is created equal. In fact, TPO is now being formulated with a variety of polymers that vary from manufacturer to manufacturer. Some of the newly formulated TPO began appearing in the RV market last year."
I believe that TPO variants started showing up in the RV manufacturing world somewhere around 2011. Your Outfitter was made way back in '04, so you have the earlier compounded polymer TPO, which is more robust when mated to current TPO-specific sealants. Now, If you have older EPDM (rather than TPO), you'll have to look into the EPDM specific caulking.
EPDM chalks like crazy unlike TPO. Try rubbing a black cloth over your roofing to see if it turns whitish.
