We had originally thought we might want to install a dishwasher after seeing them in Class A RVs. It was one of those “let's see if we really miss it” kind of things. While it would be nice to have, we haven't missed it very much. Kind of keeps one motivated to wash them right away after a meal. We're not sure where we would install one even if we wanted to. Don't think it would fit anywhere.
Have you thought about installing a dishwasher?
