Hi Vic,
I have the Dometic SMEV single burner/sink combo. We never cook in the camper and only occasionally heat water for coffee or doing dishes. I'm not that comfortable having the cooking smells in our sleeping space.
Originally I wanted to get just a sink and no stove. But when I found the single burner one I went ahead with the combo model.
To answer your question, the sink is great. I like having the faucet control the pump. The little pump button on the gauge panel is disconnected. I also like the dish drainer on the side of the sink. On my version, it covers the burner.
