I don't know where to begin looking for these drain lines..has to be between the slide floor and underbelly top, if that makes sense. Any help would be awesome>

Not trying to sound like a smart a _ _, but you will need to start crawling around and maybe pulling stuff up. Is the shower on the opposite side of the coach from the sink? If so, I would start with the one that is closest to the leak. Of course, water runs behind the scenes and can be coming from anywhere. I'm assuming you already looked under the sink. I know my sink cabinet bottom shelf can be removed by removing a few screws, so I would at least follow the drain line out as far as I can out of the house. I have an access panel for my shower, so I would remove that and use a flashlight and feel around for water there (not sure if you have one). If confirmed no water in the house, then I would try to trace the lines from the gray tank unless you can eliminate larger sections of the lines another way. The leak may be right above the compartment you are getting water in. Maybe you can crawl under the coach and see the top of that compartment from under the chassis. Of course, be careful doing that. Good luck. I'm sure you'll get to the bottom of it.
Also, do you have drain lines for your AC? I don't, but some people do and they do get plugged and back up. Just a thought.
