I’ve come across this discussion a few times in recent years. Good info.
One brand I feel worth mentioning is CTM
Marine. I bought their 16000 BTU unit earlier this year, replacing a Dometic DTU16.
After running the unit all summer without even a
single hiccup, I can say I feel good about my
purchase. It's quieter than the Dometic, cools just as well, and was a literal drop-in replacement. Great pricing on the unit too.
Had to wait a couple of weeks to get it, but that seems to be the norm nowadays.
