I just use a LG stand alone unit from home Depot, we only need it a few times a year,. But when we do it's a life saver!

I wish I would’ve bought the Coleman . I just replaced an old Dometic 16,500 on our boat with a new same size Dometic. I don’t think it cools as well as the old one. It’s quieter outside but just as loud as the old one inside .

I saw several Mitsubishi Slim split air conditioner systems on the US CGA Barque Eagle while it stopped off in Port Canaveral last year. Apparently it is air conditioned and some areas are cooled by standard residential split systems.

I have a coleman 15k BTU and working on some modifications.
If you take the cover out it flows 4x more air so I'm working on this modification. The difference is insane. You can also test this by simply removing your cover(almost all of them work this way) and turning the unit on. Prepare to be blown away.

If you have one of these units you need this in your life.. Trust me.
The stock thermostat in most of these units shuts down @ 78 degrees so you can modify the analog or wire in a wall mounted thermostat that will actually shut down the fan when it's not cooling.
You can also wire in some ducting and a 12v bilge blower for the rooftop parts.. Really helps not only the unit but to pull away the hot air so you can use it while on the flybridge.
Mine has lasted about 6 years without any sign of quitting FWIW.
Once you do both of those things I really say it's the best bang for your buck. They are loud but once you get them running right and a thermostat wired up they don't have to run 24/7.

Boat docks may have the same electrical hassles as RV parks.
Low voltage , so hard starting.
Any good RV sales site will have the published specs for many RV units.
The Air cond. built to start very easily , with soft start packages should be first choice for a cruiser.
For a dock queen with great voltage at home port might consider the larger units .

I run my coleman 15kw and LG 8000btu that I run at the same time with all my other electrical on my 5kw kohler.
I have to shut one off to run the stove or coffee maker. Might be useless info but might be helpful for some.

I ran 2 1500w units in my 50' houseboat for several years. TPO had installed an overly large genset, so power wasn't a problem. They were noisy, but performed well. I had to replace one unit after 6 years; no telling how old it was. They are disposable. If you install one, follow directions and move the temperature sensing bulb from is shipping position. My would cycle quickly until I went back and placed the bulb in the return air path where it belonged.
