The water pump always went “chug, chug, chug” and it also started making weird electronic noises. It was still working, but I thought I had better get it replaced while I could. You know how these things are, you will be out in the middle of nowhere, and…. fail! While I was at it, I also got another DC cigarette lighter plug put in at the dinette, so I can plug in my 400W inverter for the laptop.
