J Barca,
Good stuff and organized in the writing, as per usual! I agree with every talking point you made. I like theoldwizard1's take on roofing, too. The cost of an inverted boat hull may be a sticking point, I haven't done the math.
FWIW, I have a seamed aluminum roof that was coated along it's life with a fairly durable coating. Don't know what the coating is but I spent many a happy minute removing it along the seams and through holes to install Eternabond tapes. My overall observation about the aluminum roof is that, if the proper sealants would have been installed in 1971, the trailer would have remained intact and no "water infection" would have taken place.
Again, I haven't done the cost analysis of aluminum vs fiberglass vs EPDM but with the rising price of rubber and oil, metal may be the better choice, assuming fiberglass would be the most expensive. I could envision a single sheet aluminum roof with CNC manipulated cutouts, a designed wall flange, and a durable attachment system to excel. The single sheet could be hoisted onto the roof frame and may be less labor than the convention of EPDM over sheet goods.
Also, there may be a time when liquid coatings outperform anything else. I know the folks with the Roof Armor upgrade swear by them and durability seems to be good.
