It dawned on me one day. They duct roof airs into the unit. But the operating (noisy)parts of the AC are wide open to the unit via the air return. Ducting the return air would help quiet the noise.
They do Duct the return air on some RV's. The MORE you pay for the RV the more likely you get Ducted return. You can easily determine if the RV has ducted return. IF it has the standard 14 by 14 inch square inside ceiling mount, it does not have ducted air return. Doug
