cleaning the roof
I have a FF-189 and weigh about 205. to clean the roof I have a long handle (about 5 ft) brush that I bought at the local RV dealer. By using the brush and an 8-ft stepladder, I don't really need to get on the roof. By leaning over I can reach halfway across, then move the ladder. Maybe a little extra running around, but Idon't trust the roof. My owners packet included a brochure from the roofing manufacturer that recommended Murphy's Oil Soap. My local dealer, said not to use anything but the solution he sells. I've used both and the dealers product seems weak and about useless. However, It's your choice.
