A/C Gasket
I'm wondering how often the gasket on an a/c unit should be checked. I live in the mid Atlantic area, ( Maryland ). The trailer is not covered. Gasket was replaced in 2016.

I think I checked mine once in the last 15 years. Since yours was replaced a few years ago I would probably check it once. Make sure that visually the gasket is only compressed about half way down. Use your fingers and see if the four bolts are tight. If everything seems tight I would put a socket on it and tighten an additional 1/8 to 1/4 turn and no more. Then put it all back together and don't think about it for at least 10 years.
