TPO Roofs
Got a quick question which I believe I already know the answer to but some of you have more experience with TPO roofs because you have them on your camper. Went to look at the Grand Design 2150 yes...

TPO is vinyl not rubber so what makes you believe the roof membrane on this GD you looked at is in fact TPO? I took a brief look at the GD website and although I could have missed it I didn't see any mention of TPO. What you're reporting you did see is not uncommon with EPDM rubber membrane but it's hard to imagine how TPO could behave like this. :h
