At the Pomona RV show last weekend I saw a Bighorn with the Whisper Quiet A/C system. Air comes out ceiling registers on one side of trailer (the entire length of trailer) and return air goes in ceiling registers on other side of trailer (the entire length of trailer). The system still seems noisy compared to other trailers what have two larger return air registers set wide apart in rear ceiling of trailer. It seem especially noisy in front bedroom. Is this just an interim build on the Whisper Quiet system or is there going to be a change? It is much quieter that the old system with return air going directly into A/C unit, but not as quiet as some other trailer mfg.
