We just purchased a used 2011 Keystone Passport Ultralite. We had a pop up years ago, so some of this is new to us. Have learned a LOT from this forum! One thing we can't figure out is how to drain the fresh water tank. The black and grey are labeled, but can't find any freshwater.
I am with the group that has the fresh water drain valve conveniently located under the trailer next to the axle, requiring a squeeze under the steps. ๐
It is a hard to reach, cheapo plastic valve, but it works.

As Easytime said, the tanks in smaller trailers is under a dinette seat or other storage area. You may be able to see the fill line going into the tank. At the bottom of the tank you should find a 1/4 turn plastic valve that will allow the FW tank to drain.

In my trailer, the fresh water drain was inside of storage area. To find it, look under the trailer for a small plastic hose hanging down. Access the nearest storage area near the hose. On my trailer, there wasn't a screw on a cap, instead there was a a plastic value to turn.
