Sundance XLT 265RK Vibrating A/C

I just took delivery on a new Sundance XLT 265RK and it feels like it has some vibrations in the A/C when it is on high. You can feel it throughout the trailer. It is not a tremendous vibration but you know its there. Is this normal? This is my first alum frame trailer and fifth wheel.
Thanks,
Curly

They are noisy, I can definatly hear mine.

Our AC is noisy and has some vibration as you discribed. I think this is typical of most roof mounted units.

Hi Curley,

All make some noise, but I don't remember any causing vibrations unless there is a dirt-dauber nest or something like that on the outside fan blade. You might pull the cover and take a look at the fan for a dirt-dauber or something on a blade.
