It really depends on how much ice you need to make. We had an Engel 40 and it was marginal... if I really kept on top of things, it was fine, but if I missed a day we would get behind. Right now, however, I'm not certain I would go with a Dometic. I don't know what I would go with since I didn't have the best luck with Engel either. I'm a bit annoyed right now...
