After many years without a washer looks like one is needed in our 1988 40' Oshkosh Grand Villa. The question is this, have located the power line and waste line in the closet to the right of the Fridge, but cannot find the water lines, did the factory put them in or just hidden?
Ours has a false floor in the closet, water connections are under there ... at least in 2001.
My water lines and electric power are under the clothes closet floor right beside the washer drain lines behind the washer. I have a 1999.I have seen some that are under the refrigerator.
My two cents.
Mine are in the little storage area under the fridge. A real pain to snake the water lines through the little wall opening between the closet wall and that storage area.
