I have read several entries regarding installation of washer and dryers in Solitude 305 REs. The entries indicated they were most satisfied with Splendide brand washers and dryers. However, from the research I've done, it appears they make only stackables or combination units. My 305 have space in the front closet for a washer on the passenger side and a dryer on the driver's side. What make and models fit in that space?
