advice on roof maintenance
Just bought a 2011 Sunnybrook Harmony 21FBS. This trailer is sweet and exactly what I was looking for in a first RV (besides my old truck camper). A little background: Trailer bought new in New Mex...

How much time do you want to throw at this? I'm guessing the stuff that is on there is some type of butyl sealant and will last a good bit of time.
To remove it will take effort. I'd start out with a chemical remover like 3M caulk remover and see if that softens it. Mechanically removing the sealants will take a good bit of time. I did it on my roof because there were a variety of sealers used and none of them worked. I ended up removing everything and then used Eternabond tapes to make sure everything was sealed. I'd bet I have over 40 hrs in removing sealants/sealing the roof.
A pressure washer can be used but only with a wide fan tip and the best use is not to try removing mold with it. For that, get a dedicated siding cleaner or mold soap and let the chemicals do the work.
