Keep the roof clean and you will have minimal black streaking...
that won't be an issue now that we live somewhere we can get the TT home for a cleaning. For the past 2 yrs, we lived in a neighborhood that we couldn't get the TT in and out of so we were stuck using the local truck wash which did us no good. now the plan is to bathe it about 3 times a year (spring, summer and fall). we also caulked the joints in the gutter where water was falling down the sides causing some of that streaking.
