OK, perhaps we don't really know what RV you have. You said you have a 2005 Minnie. And, I guessed it's really a Minnie Winnie Class C motorhome. Because when I search 2005 Minnie that what I get. Is that correct?
If that's so, then there is a screw off plate on the bottom of your Wet Locker that reveals the hole for the dump hose.
If that's not the RV you have, you'll need to get back to us with the EXACT model info.
Here's a photo from the 2005 Minnie Winnie Operator's Manual:
