[Carl n Susan]

I have no idea where the fuse panel is on your rig. It probably is close to the front door but that is a guess.

The WH is located on the exterior wall between the couch slide and the refer slide. That peninsula island with the quasi curio cabinet above it covers the body of the WH. That lower cabinet is the one that has to be opened up to access the back of the WH. There may be a removable shelf in the lower cabinet whose removal will allow access.
