Hey guys, new to the forum here and new owner of a fifth wheel. I just bought a used 2021 Dutchmen Astoria 3553mbp and had a question about the dump valves on it. So the specs for the trailer say there is one 78 gallon grey tank and one 39 gallon black tank. In the wet bay there is a pull handle for the black tank and one for the grey tank as well but underneath the trailer there’s another pull handle for the grey tank. Is there actually 2 grey tanks? One for the kitchen and one for the bathroom? The one underneath is under the kitchen Just confused due to the spec’s saying there’s just one grey tank. Any help would be appreciated. Thanks!
