Our RV has a gutter/awning rail on one side that channels the water away from the windows and such just fine. Unfortunately they did not install a drip rail on the driver's side of the RV. I have about 20 foot of rail. There is a trim strip on the driver's side that holds down the rubber roof. I've found options to replace the rail with a full drip railing but I'm a bit leery of removing the existing railing due to the age of the RV (strength of the luan where the screws are attached) and potential issues with various adhesives that are likely under the rail.
Others feel free to chime in if my concerns are unfounded.
The alternative I've found thus far are the "EZE" gutters that are available here or other RV retailers.
Essential Products RV & Marine Perhaps others have found good solutions/alternatives? My only concern with these aftermarket options above is that my gutter run will be 20 feet long in a straight line. These use foam adhesive and even after prepping the fiberglass with alcohol, I'm wondering how straight the installation turns out as this comes on a roll. I could install it on the metal trim instead, but it would cover the screws if ever they need to be removed for replacing the rubber roof.
For folks using EZE, what has been your experience if you've had it installed for a few years?
Other options? Input is great - thanks!
