I believe this is the correct model.
Some suggestions.....I don't know why, but Newmar does not connect the dishwasher to the inverter. My guess is that it pulls a lot of power while drying and it's probably not good to have it stop mid cycle, something that could happen more easily while on inverter.
There is also a drain fitting that Newmar uses that connects the dishwasher drain hose to the sink drain. It's a black pipe "T" that has a 1" hose bib for the drain line. I don't know how hard that may be to find. I'm sure it can probably be connected with some variety of fittings, but the one Newmar uses is probably the best way to do it. I can take a photo of that fitting if you need it.
