2016 3710FL tank valve locations

[gwsmith1]

We purchased a 2016 3710FL to replace our 2005 3450 and it arrived this weekend. I am not able to find, however, more than one tank drain valve. The one I found is I assume to be the one for the galley tank since it is located toward the front by the water hookups and controls. Granted it was cold and rainy so I did not crawl completely under the trailer but I give a thorough look around the whole thing, thinking that they should be located where they are relatively easy to get to. Our old Montana had 3 tanks/valves, one each for the black,grey and galley and I do not recall ever coming across a rv that didn't have at least 2, 1 for the black and 1 for the grey. Any thoughts or suggestions ?

Thanks !

Well the seller got back with me and said that it was inside the sewer hose compartment. I have never seen one there but you learn something new everyday. Since I used my existing sewer hose I didn't even think to pull the one out that was in there and look.
