We have a 2015 22R. In our rig there are two winterizing drain valves under the rear most bench (next to closet). These are on the floor mounted in a routed channel in the floor. They both should be turned downward, vertical is in drain mode. I believe the handles should be facing towards the outside in a horizontal position. I put a dot on each one showing which it should be for normal operation. I also "thinK' they can be turned the wrong way which likely shut it down. All of the bath water lines originate under this seat. My rig does not have cutoff valves just for the bath lines.
There's also a winterization bypass valve on the back of the water heater. If that is off you would have cold water at the kitchen on the hot side. Assuming the water heater is on. Make sure there's water in the heater before turning it on.
Let us know what you find.
