We have a Raritan Marine Elegance on a 99 361 with smart controls and love it, no more explaining how to use the head and "simple" push button controls for visitors. I can get you some pictures if needed, the space is not overly large but its definitely possible we had ours for years now.We also have a electro scan instead of holding tank and love that too.... My future plans are to move to composting toilet if my marine area turns no discharge for even my processing plant, I hope it doesn't come to that but I'd probably head that direction (pun intended)
