A Forest River rep replied to my email question. The answer is Alpha Ply. She directed me to the manufacturer for how to care for it.
Product Care & Warranty - Alpha Systems, LLC
A word of caution because, the final sentence on the care document says "
Alpha's membrane is quite inert and will resist weathering well. It does not require the periodic application of products to protect it from ultra-violet light or ozone. In fact, these products can often cause damage to the roof membrane. "
I hope this helps someone else in the future.
