On TV tonight John Wickersham complained that a used Coachman Amara had rear exit for waste water,on the basis that on a sloping pitch it could be difficult to get water to drain. We have rear exit pipes and have never had a problem. We usually have a levellish pitch and having the waste water exit at the rear means the waste water containers are out of the way when parking the car on CC pitches. Also CC service pitches we have used have the drain at the rear of the pitch so the pipe work is shorter, means our water drains away easily. The side draining pipes on these service pitch end up with longer runs and i often see the lengths of pipe lying on the ground, plainly not draining the water away, so I prefer the rear exit pipes every time.
