SemperFi, I just had the FlexArmor roof done on my 2014 38RE. And I could not be happier!! John Fisher and his crew in Prescott, Az did an amazing job, he communicated very well, kept me informed of any other issues that could come up during his process (luckily, I had none). You won't be disappointed with this system. I'm not sure what part of the U.S. you live in, but John has another location in Denton, Tx (Dallas area), I strongly recommend him personally. It wasn't cheap, but not much more than replacing the rubber membrane.
