Joe,
We had a U-Line icemaker in the previous coach and we have a refrigerator with and icemaker in our current coach. We did not and will not use either because we cannot adequately sanitize them, and if we did use a chlorox solution to do so our iced tea would taste like a swimming pool because you can't run water through them to flush them out adequately.
If we were full timing or staying in the coach for an extended period I might assume a different opinion. For now Di brings ice from home and makes it in trays using our RO water from home.
And Paul is right, I did calculate the ratio of chlorox to water, but I have no clue where I read it it was so long ago.
