I have a Leer fiberglass topper on a Tacoma and live happily out of it most of the time. When it rains, though, and I have to open the rear hatch of the topper, the rain hits the ends of the hatch hinges and drips through directly onto the truck bed (in this case my mattress). Does anyone have experience with successfully adding a rain gutter to the exterior topside of the topper? Or have experience solving this another way? My top option at this point is epoxying a strip of weather stripping to the exterior of the topper channelling the water out. Thanks!
