Yesterday we replaced our front air conditioner with the Eco-Cool 15k BTU unit .
This thing is incredibly quiet . Installation was fairly simple and straightforward .

I like that you don't need a soft start with this one. I have two on order.

We are really happy with ours . It blows cold and is very quiet . Running down the road you can't hear it . Cat was in the front of the coach talking at normal conversation level and I could here her from the rear of the coach , that was with the unit between us on turbo mode . Also , I could feel the cold air blowing into the bedroom from the front .
The rear unit is the low profile 13.5 Rec-Pro which is also quiet , but not as quiet as the Eco-Cool . I checked our total amp draw with both air conditioners on high with the compressors running along with our residential refrigerator and the battery charger . Total amp draw was 28 amps with all those running .
