While mini split units have been primarily used in homes their high efficiency makes them ideal when installed on an RV, trailer or camper.
They have become very popular with RV and trailer owners since they are much more efficient, and work much better compared to rooftop units that come installed.
Mini split units are well known as being highly efficient with very good SEER ratings.
Since they have such high SEER rating they have a very low amp draw.
Many homeowners use this high efficiency to drastically reduce heating and cooling cost.
While most mini split units are not specifically designed for a motor home or RV many people have installed and retrofitted them into place.
Most often the outside condenser is set on the tongue of a trailer or a hauling hitch for an RV.
The copper line-set that goes between the two units is usually fed underneath along the frame and up through the floor to the inside unit.
There is no set way when retrofitting a mini split, with no-doubt many creative ways to fit a unit into place.
With that in mind below are some units and methods others have done to retrofit in a mini split to their RV or trailer.
As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure a unit is a good fit for you.

Any install for an RV or trailer will need to be thought out more compared to any home installation since it will be on a moving vehicle.
There is many creative solutions to installing a mini split on a motor home.
The installation will need the outside condensing unit set up to blow away heat or cold while the inside unit will need to be mounted with a bracket on a wall.
Two small copper lines called a line-set will need to be run between the two units along with control wires.
