And right back where I started. Ran well off/on the first night and part of the next day. Then it started making the same noise as before.

Dometic RV AC noise after starting

So, this is what it sounds like.

Sounds to me like after running for a bit the compressor then seized up.

It's just a guess on my part (but I've been servicing HVAC/R equipment for over 50 years) that the compressor is going bad. According to the video, that sound is coming from inside the compressor. If it is, there's no way to fix it without replacing the compressor. Before you do that, compare the price of replacing the compressor with the cost of replacing the whole unit.

Thanks guys. That was all I could think of also. And DFord is correct, a new upper unit is about the same pricing. Next question, can I install the 15Kbtu in place of our 13.5Kbtu; without making any electrical changes?

The compressor is going bad. Replace the entire unit. The 15K unit is a direct replacement for the 13.5K unit. Just bolt it down and connect the same wires.
