Residential air conditioner failure due to off road vibration

I have heard it proposed that residential A/C units (window/split) will fail when used on RV/Expedition vehicles due to vibration.

Does anyone have any real data on this?
 
I have never seen a mini-spit installed in an RV, but there's plenty on YouTube. The only window units in an RV I've seen installed are in RVs that never move.

If you did get one installed, true off road vibration would be terrible. A maintained county dirt road would be rough, but an unmaintained sixty year old trail is something different.

Here's a guy that did a decent build and talks about window units:

 
Jason is the outlier on this, but having met and chatted with him, I take him at his word.

IIRC, Earthroamer long used window air conditioners in their vehicles.
 
A window unit is not something I would consider for my RV trailer. The mini-split is something I'm considering. I don't think it would be an issue.
 
I would definitely add some kind of rubber vibrational dampeners to ANY large, heavy, piece of equipment with moving parts that is subject to serious vibrations.

I'm mentally picturing something like how an engine is mounted into a car with rubber / hydraulic / spring brackets.

Trailer AC is my next project.
