wouldn't be on my list to consider due to their roof design. Their method of attachment and required maintenance - and what potentially happens if there is a breakdown in the required maintenance, is something that would have me looking elsewhere. Please feel free to do a search and see if it's something you're OK with. Many are.
With that said, I also wouldn't get too hung up on needing to be a "one piece fiberglass roof". Just because it's fiberglass doesn't mean it's quality. Some of the fiberglass that is installed is virtually paper thin. Keep in mind, fiberglass also breaks down over time, and the thinner it is the faster it breaks down.
Our MH has a BriteTek roof. This is our 3rd one with BriteTek, I would order another without hesitation. When we ordered our current MH a one piece fiberglass roof was available, based on our prior experience with BriteTek we chose it over fiberglass. BriteTek is NOT a rubber roof, it is a synthetic membrane. Newmar uses the BriteTek brand, many others simply call theirs a TPO roof. There are differences between TPOs as well.
We've had rubber as well, on both a MH and TT. I would not consider anything with a true EPDM rubber roof.
As far as the MH itself, most us a laminate construction, a few use hung wall. If it is laminated it can delaminate. Hung wall can't. Those using hung wall are Monaco/Holiday Rambler, Newmar, and Travel Supreme/Entegra. We have owned a delaminating MH and I have worked on delaminating motorhomes and TTs. Unless you're getting into a true bus builder, for my money I will pick hung wall construction every time.
There are 24 hours in every day - it all depends on how you choose to use them.
