I did carry a telescopic ladder for a while, but it still took up a fair bit of space and I hardly used it.
I can normally find a wall or something if I want to clean solar panels. Rest of the roof can wait.
Nothing shifts the crap on my roof. Ive tried all these magic spray and leave thingys, all sorts. Even the local dealer couldnt shift it. Its just a badge of Honour now. I just tell people I did the Paris Dakar Rally in it and its just the remnants of a plague of Locusts.
