I have a Elkridge 29RKSA with separate gray tank outlets. It's a pain to hook up two sewer hoses from the gray tank outlets or switch the front sewer hose to the rear then switch it back again. Has anyone with this set up plumbed the rear outlet to the front outlet. Seems like it could be done as the Big Country has the same floor plan but a single discharge outlet for both tanks. Any ideas would be helpful.
