To use it, just slid the cut portion under the edge of the roof between
the roof edge and bunk end. YOUR AC RUN-OFF WILL FLOW RIGHT
INTO THE PIPE AND ONTO THE GROUND!!! One important thing
to remember is to when setting up the camper be sure you have the
camper set up where the water will run off the roof in the direction
of where you will be placing the pipe. This little of an angle will never
be notice in the camper !
