I have had two Mountaineers, a 2010 and my current 2014. Both of them had a convenience center behind the storage compartment door where the black and main grey tank valves were located as well as the tank fill switches and the fresh water and black tank flush connections. The galley tank valve was located outside of the convenience center under the frame near the drivers side front wheel on both rigs. If your main black and grey valves are outside the storage compartment door and mounted under the frame, it is likely someone converted them from a cable pull to a threaded rod system.

My 2014 door is deliberately designed to be hard to open and close, as they eliminated the stop latch.
