Thanks, guys, it sounds like you were right. Here is the response from Amber at Keystone:
"If you are at the foot of your bed the water pump is on the left hand side of the bed, there could be a box like structure covered with carpet you can lift the carpet and you will find an access panel, if you do not have a box like structure next to your bed, then the pump will need to accessed through the storage compartment. If you go into the storage by the shoreline electrical plug, there will be an access panel on your right hand side, you will need to remove a few screws to remove the panel to see the pump."
Headed back to storage today to finish winterizing. Thanks again.
