Hey Everyone, I have a 2011 Viking Epic 1906st that I’m going to be remodeling this fall/winter. I had a crazy idea and wanted to see if it has been done before. I’m not a boondocker, so we will probably never use our fresh water tank. Could I convert the existing tank to a gray water tank? I would probably need to have the drain run out under the pup (like on a traditional travel trailer). I want it to be able to hookup to a sewer hose for full hookup or dump station with a valve to close it if I am not at a full hookup. Thoughts? Warnings? Advice?
