That would be my concern. I don't know how well the compressor and other "outside" components would handle all the rocking and rolling.

I have a two unit Daiken mini split in one of my rentals. A larger unit in the living room, and a smaller one in the master bedroom. They installed the whole thing in one day. The tenants love it. Very quiet heating and cooling. Very efficient as well. One drawback is the other two bedroom doors need to be open to receive the benefit of it. In Oregon, there was a state tax credit for it. I don't see why it couldn't work well in an RV if it was well secured. It would certainly be much more quiet than the stock furnace that blows more noise than heat.

I was talking to an A/C tech about mini splits. He said most are made in China by the one company and branded with many brand names. They generally work well.

He said the one thing that you should check in the owner manual is the chart that says "Room Temperature" and under that "Outdoor Temperature" to make sure the Outdoor temperature range says 122 degrees. Apparently some are sold that are good up to 108 degrees and the thermal cutoff will shut it down above that temperature.

Mostly correct ! The well know brands in the mini-split business are Mitsubishi and Fujitsu. I am pretty certain they are NOT made in China !

One issue with any heat pump is low temperature operation (heating). Many do not generate significant heat below 30F-40F. Some go much lower (below 0F). It is not easy to understand the specs on some of these so you may need to consult an experts.

Most manufacturers do make A/C only versions of the same units and these are less expensive.

12VDC A/C or heat pumps are still very expensive. (Believe it or not most actually have an inverter built in that creates high voltage 3 phase AC !)

Unless 12VDC operation is a must, stick with 120VAC.

Well Sir,
To see how well all those type of components work, in an RV type situation, just look at the thousands of Winnebago and Itascas that were produced from around maybe '00 to about maybe '09 or so. A very, very large percentage of those coaches, were made with "Basement A/C" units. Those are almost the same as a residential mini split. And they are close to regular residential units.

But, in any case, the compressors in those basement units, we have one, last and handle the rocking and rolling that RVs instill on them without issue. Our coach, an '04 Itasca Horizon 36GD with the CAT C-7 330HP, has the basement A/C and at around 15 years old and 89,000 miles of "less than perfect American roads and freeways", that basement A/C is still putting out "tons" of cold air.

We gave 3 mini splits in our house in Mexico. None were made in China. They are great and Workin over 110 temps. But I doubt they would survive in an RV environment. The 110 volt Mexican units sell for around $300.
