Ductless AC instead of roof mounted AC
In addition to my roof repairs I am replacing the AC unit on my trailer. Does anyone have any experience with the Mini Split Ductless AC Heat Pump reliability on an RV? I have seen installs on youtub...

The sizing might be pretty close the old AC coming out of the camper uses a RK160AT-024-J7 compressor rated at 115V 1hp and 13k BTU.
If anything it may be a little bit too small at 12k BTU. Thoughts?????
I'm getting mixed messages.
Conversion charts show 6k to cool 150 to 200 sq ft.
Check the chart on the bottom of the page. I have 147 sq ft to cool and heat. 12k puts me about 3x the rate they recommend.
I should be able to hang meat, lol

If I need to reduce cooling I can block the intake some or slow the fan or put in a smaller expansion valve. If I need more cooling well too bad If I don't get a large enough unit.
My wife has to have the noise from a fan to sleep so air circulation into the bedroom should not be an issue
The line set will travel straight to a 36 inch wide floor to ceiling closet and then down to the floor level passing under a couch/bed and then out the back of the camper to the outdoor unit, two 90 degree sweeping bends. I will buy copper and insulation from my local ac supplier to make the line set. It will be encased in a cut resistant sleeve and supported by straps every foot or so.
The condenser water drip line will follow the same path until it it is about 3 ft behind the tires and will then exit the floor of the camper.
To stabilize the compressor unit I plan to mount with rubber bushings on the bottom and screw on a bracket on the top and use rubber bushings there as well. Movement in all directions should be restricted to less than 3/8 inch and will leave the last 2 feet of the line-set to have freedom of movement. If the line-set fails it should be at the last rigid support.
The connections are single flare with a plastic bushing.
It is nice having some one to bounce ideas off of thanks to all!
