Hope you fixed the leak, sounds like you have.
So far so good with the Miramar. Have not used it a lot due to Covid. I think about 4-5 trips so far, longest was from NC to Key Largo. Planning a trip to Maine this September.
Somewhere around 20 modifications so far.
Starting to work on DIY Magnashade at this moment.
May add third AC and a half dozen other mods in the future.
Keep it between the ditches.
