Following Mowin's post of adding 2nd A/C, I am also going to add a 13,500 btu non-ducted in bedroom of 5er. The players appear to be Dometic, Coleman, Advent, & Atwood. My question is does anyone know what unit is the quietest? Don't care about ease of installation, cost or anything else, just the quietest...

Of the ones you listed, I would say go with the Coleman or Dometic. The Advent is a Chinese knock off. Check reviews on line before you buy.

Dometic's heat pump which goes by a different brand name.

We had a Coleman that did not last one year, the Dometic lasted 14 years of desert heat, the Colemsn was only good for temperatures less than 85f the Dometic keept cooling even when we had 118f the interior was cold, my C has about 1 1/2 inch insulation and that helps, replaced Coleman that quit working with Dometic.navegator

Who knows who actually made the Coleman thing.

To answer your original question without making value judgments, we have owned 3 of the 4 you listed and the Coleman (@ 15K) was by far the quietest.
