We had the same fresh water leak the first time out. As of the last trip we didn't have any issues - there were a few issues that were fixed under warranty from the dealer.
We have the "bar" fridge, the access door is not vented. We haven't had any issues with the fridge, except that it is kind of small. On our last trip we camped out with another family, they were in a tent. So we reserved the fridge for food and kept drinks outside in a big "4-day" cooler.
We are happy with our trailer - the memory foam mattress we bought on Amazon increased the comfort level by 100%, the trailer is now more comfy than any hotel
