Stick on gutter - How about roof instead of side wall?
I have new-to-me motorhome, and am plagued with white streaks running down the side after it rains.
Doing some research, I find flexible press-on RV gutters. They get cut to length, and pressed on to the sides, front, and rear to direct the roof runoff to the corners of the coach.
As I was contemplating this, a thought came to mind.
Why couldn't they be attached to the top edge of the roof? The roof is sloped, to each side, so no water would pool. I'm fairly certain no RV is ever 100% perfectly level, so rainwater would naturally migrate to the front or rear of the coach.
It would be using the gutter more along the lines of a water diverter on top of the roof, as opposed to a gutter on the coach sides. Hope I'm explaining well.
