What real advantages does TPO have over EPDM? With either you have the exact same major thing to deal with and that is sealant maintenance. The EPDM gives up material slowly which is part of its aging process, but TPO ages and turns brittle from UV exposure. In either case both have a 10 to 15 year lifespan normally, which can be increased with care. A lot of manufacturers now use Alpha Systems Superflex, which is neither an EPDM or TPO. Time will tell as to it's longevity as far as membrane is concerned. You still have sealants to maintain.
If your looking for something else, fiberglass, Aluminum, etc, then your eliminating probably 99% of all towable RV's from your options.
