Which model? Mine is a 2012 model but is the 2011 design if that makes sense....they seem to be quite liberal with their years. I asked AF service about coating the roof and they said not to. They said clean it with a mild detergent and a brush and let it go at that. To me, that doesn't make sense if there are products that can help the life of it
I just did a bit of research. Some people claim up to 50 years of life. Realistically, about 15 years so you are there. They say just to use the Dicor product in everything I read, but maybe if you are beyond that, maybe something is needs to be done. Good luck with that.
The guy who runs the site is a good guy. His name is Adam. I've been to a few of the rallys. They do them in LaGrande, Oregon where the trailers are made. Usually have a couple of plant tours and a bunch of other activities. I haven't been in a few years though.
There are a bunch of Henry's products for all types of roofs. I don't remember the number for the EPDM roofs. 887 maybe? I'm going tp try to get it done before winter sets in.
I will be sure to go back and checkout the site. I have questions about my AF and other than asking the dealer or the factory I wasn't able to get help. For instance, the AF rear bumper isn't a standard 4", but instead 4.25". The owner had lost the cap for the end of the bumper so he wasn't using the bumper for the hose.
