Our 330rlts leaked out of the underbelly when washing out the black tank.
Where the black tank sprayer enters the tank there is a nipple that needs to be removed, put teflon tape on the nipple and reinstall it. (As Lady Fitzgerald said you will have to drop the underbelly to get to the nipple.) Make sure your underbelly insulation is dry or it will mold.
Do a search for black tank sprayer.
