I have a 2015 Thor Majestic 28a from Cruise America (two actually). I recently completed a Dicor
roof resealing project on it. Before starting on it, I wanted to confirm exactly what type of roof was on it.
It was suggested that I could remove one of my interior vent trims and see some of the material to know if it was EDPM or TPO. (check youtube) Unfortunately, when I tried, there was ZERO material visible.
When I bought my RVs from Cruise America, they made a big deal saying that their roofs are something special, so I was worried that perhaps they weren't EDPM or TPO but rather something else. I wanted to make sure it was okay to use the Dicor EDPM/TPO roofing material.
I read online somewhere (maybe even in this thread) that someone mentioned it was TPO. But I didn't want to believe just one person posting online to make my decision (no offense), because if it was wrong it could be bad news.
Well....it took many many calls to multiple Cruise Americas to get the answer. They told me that on the 2015 Majestic it uses a TPO roof. Interestingly, they said that their 2020 model (not sure about future models) is EDPM.
Just wanted to throw this out into the universe as it was much more difficult for me to find this answer and I'm hoping someone else finds it useful.
Happy RVing!
Chris
