Hmmm .... but how do you get OFF that ladder and onto the roof, and even more tricky ... get off the roof and BACK ONTO that ladder??
When I get up unto our RV roof it's to crawl around on hands and knees so as to wax it or repair something, so I have to be "fully up there" ... so to speak. I can't be only reaching over a couple of feet from a ladder I'm standing on along side the coach.
I'm only around 230 lbs., but have never felt like the ladder that Winnie installed on the back was going to pull out - it has never become loose at all in eight years of use. I think that the ladder is (had better be) securely fastened to the aluminum framing inside the coach walls.
