I have a question about the new Thermo King SB230 trailer unit. I just purchased a new trailer
and had a TK Sb230 installed on the trailer. I ordered the Unit with ETV & Whisper. But, when I went to pickup the trailer, I noticed that it did not say "Whisper" on front of the unit. I asked the
dealer and he assured me that "Whisper" was installed, even though, it does not say so, like
many new units I have seen. (Dealer told me that, all new 230 units that have ETV installed, have Whisper.) Is this the case, and how can i tell if "Whisper" is installed on the Unit.
